- เผยแพร่เมื่อ 6 ก.ค. 2024
- Its time for the next modification to my Mini R59 JCW Roadster. This time I am going to replace the differential. Questions is though...what is a limited slip diff, how do they work, how do they improve the car, which type should I buy and how are they made ?
I was invited to Quaife, specialist diff and gearbox manufacturers, for the tour of they factory and to find answers to all of my questions.
Thanks to Quaife and Lohen Mini for arranging the visit.

No kidding, that was like watching a BBC documentary (in a good way). Appreciate all the hard work you put into your videos 👏👏
Wow...thank you 🙏
Most of us don’t know how much work goes into the making of the parts fitted to our car. The skill and the work was phenomenal. Excellent video Peter.
Cheers Kevin. Impressive indeed 👍
I don't even need to watch this video, fitted one to my Honda Integra DC2 SI as it was an option my car didn't have, got the Quaife fitted and wow!!! Any FWD or RWD without an LSD is really lacking. For example any BMW M products. 👍👍👍
What a brilliant engineering company. Who says we import everything.....nice one
Exactly...they are world leaders 👍
I'm surprised the UK economy, business rates hasn't crippled the company like it's doing to most long standing companies in the UK.
But when the banks fail the government jumps.
And very expensive
@@jameswilson8820under 1k for a unit expensive? You must be a Yorkshireman.
My standard diff is £400 a ATB £950 I think that is great value.
I recently fitted one of these to my Mini when I replaced my clutch. Hands down the best mod I’ve done. Expensive if fitting on its own but if you fit it at the same time as a clutch (as I did) it was only an extra hours labour. Lohen fitted a TTV Racing clutch to my car at the same time and it is completely transformed. Rather than understeer, you can feel the car pulling you round corners. It’s ace!!!
Yep 👍
Blimey Pete, your content just keeps on getting better! What a brilliant and informative video, looking forward to part 2!
Thanks Nick, kind of you to say. Part 2 should be good but Part 3 (Driving) is going to be the best. Can't believe the difference !
Nice unit. Good to see manufacturers willing to support their own country. Very good product as well. Thanks for putting this video together mate.
My pleasure 👍
Brilliant content Pete. Respect to the folks at Quaife for the quality and attention to detail. Thanks for educating me.
My pleasure. Glad you enjoyed it 👍
Brilliant video and a real insight into differentials and how they work. A brilliant example of the precision design and manufacturing engineering this country is capable of.
Cheers David 👍
Very interesting video. I remember back the the 90’s when I was a young Plant Operator Mechanic learning my trade in the Royal Engineers. One day we were taught about epicyclic gear boxes with the moons and planets etc. You have never seen a classroom with so many confused faces. Happy memories. Keep up the great videos.
Brilliant. Love this 👍
I bought a mapped E92 330d a couple of years ago (still own it) which has a lot of torque. Great car but let down by serious traction loss, especially in the wet. A quick visit to birds the bmw specialist and a few hours later I got it back with a quaife atb. What a transformation!
Anyway, great to see the factory and the manufacturing process that made my LSD. Thanks.
Great to hear that. They make such a difference don't they 👍
Fascinating video. I remember rebuilding the transaxle of my first car (Hillman Imp) after the casing broke and understanding how a standard diff worked. That was *cough* years ago and gained so much knowledge over the years of ‘tinkering’ . Thanks and keep them coming.
Cheers 👍
So interesting. Props to Quaife for having a great host to explain everything so well and you for the great questions!
Thanks Oscar 👍
Morning, driven lorry to Faversham, come back, then spent 2hrs clearing conifer clippings up! Got home at 4:15, then got the wheel barrow out! Showered and now laid in bed. Very cool and informative video sir.
And you broke the wheel barrow 😂
Petrol Ped, bloody thing lol.
Brilliant video Peter, a really interesting insight into the product and the processes involved in manufacturing high quality components. Something this country was a world leader in & will be once again. Makes me feel proud to be British.
Thanks to all involved & to you for sharing.
🇬🇧🇬🇧🇬🇧🇬🇧🇬🇧.
Geof
My pleasure Sir 👍
This is what i love about your videos Pete , So informative and interesting .. Great work mate !!
Cheers Lee 👍
It's been a while since I've watched one of your vids Pete, excellent as ever my friend. Glad to see you are still making them and hope it is all working out well in your new chosen career. We have two things in common I never realised, I am also from a production engineering background AND I have a Quaiffe ATB diff in the back of my road legal track car! I now have a much better understanding of what's going on inside it now thank you very much!
Cheers Steve...welcome back 😜 Things are going well thanks. 3 vids a week now !
awesome video! very cool to see inside of Quaife's factory
Glad you enjoyed it!
Fascinating. I had a Quaife LSD fitted to my mapped E92 335d 10 years ago - the difference was amazing. Incredible amount of work going into each one - I am surprised they are not more expensive having seen the video!
Me too !
Did research on this and went with one. Haven’t put it in yet. March will be replacing the clutch with performance one, seals etc….
Will do sc service not just the oil. 15% pulley , cam upgrade , cam chain, balancer , gaskets & seals. Bigger aired intercooler too & more.
With that I decided on an LSD and was told about these. Seem to be above the rest. Can’t wait for the results !
You will love it 👍
I put a Quaife LSD in my Merkur XR4Ti. What impressed me the most, was how when I would take corners, the inside rear tire, would squeal ever so slightly because it would drag the tiniest bit. I was able, because of this, to corner much much better. Of course my 0-60 time increased greatly and my 60ft time dropped by quite a good margin as to be expected but I never expected the handling to improve as drastically as it did. It was as if the car wasn’t just driving on rails, but GLUED to the rails. Best diff company in the world hands down is Quaife.
what do you mean by your 0-60 time increasing? so acceleration is weaker after this?
Brilliant film Peter and a fascinating insight - gotta love precision engineering... that was off the scale!!!
Wow, cheers Paul 👍
Great video, thanks! I installed a Quaife diff in my Fiesta ST and it has been transformative. Cool that several of the parts in the video were destined for FiSTs. BTW, when my wife and I were recently visiting England we rented a manual RHD Mini - I loved the challenge of shifting with my left hand for the first time in 44 years of driving manuals!
The first time you drive on the other side of the car it's a fun challenge 😜👍
Just stumbled across your channel yesterday and binged on your videos. Loved the "How to become a Racedriver" series. Keep up the good work!
Oh wow...welcome to the channel and so glad you are liking my videos 👍🙏
Awesome video Pete combining my job and hobby, manufacturing and cars. The skill level for gear hobbing and CNC machining is top notch 😎, serious respect for Quaife.
They are top of their game 👍
I added a Quaife ATB LSD to my '13 Focus ST about 5 years ago. The big plus is it nearly eliminates the prominent torque steer that the stock car has. It definitely helps put the power down on the pavement too. Pulling through corners is much smoother and less hair-raising. It was well worth the money and if I had to choose between the LSD and the MP-275 tune, I'd have to pick the differential.
That was really interesting. Loved that. Plus, I'd love that open diff model on my desk... That was a work of art 👌🏻
I'd be playing with it all day !
Another great video.
Have driven a plate and Quaife diff in a front drive car. On a track only car the plate diff is the way to go, but you would hate it on the road. The Quaife however is great on the road and not that much behind the plate diff on the track.
It has made such a difference to the Mini 😳
definitely on my list of mods for my Roadster. Thanks for this video and helping me understand just what a limited slip diff is, how it works, and why it's a necessary modification. I can really understand the safety aspect of having one now, especially with as much as my roadster seems to just slip and stall while trying to turn from a side road onto a more heavily traveled road and having to do so quickly (blind spots and all due to terrain and vegetation)
Glad I could help 👍
Wow awesome vid fella, we’ve watched it about five times now. The explanation was just excellent. Keep up the good work 💋
Thank you 🙏
Loving this, LSDs are a black art but the gains are incredible 👍🏁
I love stuff like this. So cool, thank you.
Awesome video. This was brilliant, so informative and great to see behind the scenes of companies like this. I love engines etc and I really found the diffs being built up so very satisfying. Would love to see more like this. Thanks for sharing. Well done.
I'd love to do more as you guys seem to enjoy this one 👍
Petrol Ped definitely, that would be awesome 😉👌🏻
Nice vid. Had one of these (and one of their gearboxes) in my modified saab for years! Appreciate them even more now 👍🏻
Cool 👍
Excellent and remarkable work of engineering. Many thanks for this instructive video on limited slip mechanical differential technology. Amazing.
My pleasure. Glad you enjoyed it 👍
Great and informative video.espefually seeing them being made. My 208 BPS has a torsen from the factory and it is my favourite part of the car - instills so much confidence, and the power just goes down, no drama.
It makes such a difference doesn't it 👍
As a qualified manufacturing engineer i love this video and as a proud owner of a JCW, I am planning seriously for the LSD mods
We have two things in common 👍
Very interesting video. I love learning how things work and how they are put together. Your content is next level!
Wow thanks Andrew, glad you enjoyed it 👍
I had one fitted into an 03 plate FIAT Seicento of all things as a group on a Forum grouped together to have one made to fit our cars, they made an impressive difference to the grip - especially with wet weather handling 👍
JEEZ the good old days when you could hear an Escort with a straight cut gearbox then watch it slide through the bends , nice 1 Petrol Ped for showing us this cheers SCOOBS UK (Wales).
Cheers Scoobs, I'd love an old S2000 👍
Liked that a lot and glad I ordered one on my Fiesta ST, didn't realise until your video that a LSD also helped with braking and tyre wear!
Yep and all the ST diffs are made here 👍
Nice one Pete, great video. It gets mesmerising watching the ceramic tumbler removing swarf and rough edges from the different components, I used to spend many an hour watching it, sad I know lol. Can't wait to see Ruby up and running with her new LSD installed, be prepared to be blown away. Take care mate 👍🏁
It has blown me away. We did quite a bit more work when it was installed. She is now finished and absolutely awesome !
@@PetrolPed
Can't wait to see you ragging Ruby now, I would imagine you've now reached the point of no more mods needed, Ruby should be more than capable of everything that you throw her at now. All the best Pete 👍🏁
Mr brain!!!!! 😆
Really nice to take the time to learn a bit about stuff I normally don’t bother that much with. Knew there are diffs, knee a LSD was better for power distribution. That was it.
Great vid and great to keep it interesting
So pleased to hear this 👍
Hi Ped
Very informative👍👍👍Excellent video, learned a lot. You keep raising the bar, well done.
Thanks Philip...just hope I can keep reaching the bar let alone raising it 😂
Quality video as always, fascinating stuff! Will be very interesting to see the difference it makes to R59 JCW. Cheers.
It has transformed the car. Video coming soon 👍
I like that everything is done by hand And not by the machine to ensure quality.
very cool, thanks for sharing!
Well done. I had a Tru-Trac differential in the front axle of a 4x4 pickup back in the 80s, but I never really comprehended how it worked so well. It was designed just like the diff you are showcasing here. Your segment showing the color-coded demo was brilliantly explained. No I get how the torque is sent across to the non-slipping axle.
BTW, a 4x4 pickup with traction boosting axles is a force to be reckoned with.
Great that you found it useful 👍
Looking forward to the install and first drive video 👍
It should be epic !
This made me very confident with my recent purchase 👌 great to see the level of attention to detail.
You won't regret it. Transformed my car 👌
@@PetrolPed awesome. Is being fitted in January cannot wait 👌
I rememeber when I was younger playing GT2, an LSD was one of the first few mods on the list because, "it felt better coming out of the corner"
Years later, owned 2 RWD cars. 1st was open differential and the 2nd was a VLSD. What a difference it made just coming out of the corner
Great video! Awesome experience.
Glad you enjoyed it!
Fascinating film Peter. Ive heard the term so many times, its really interesting to find out what it does and how it works. Maybe you could look at doing a few more like these.
I would love to do more. Really enjoyed making it 👍
Fantasic, more engineering vids indeed, I really really didn't know what the LCD looked like and kinda only half an idea how worked, NOW I KNOW, mega
That has made my day 👍
Very enjoyable video (like you also trained as an engineer) this really showed of your presenting skills and getting the technical information across in an understandable format.
Cheers Bud 👋👍
Very interesting to see inside the Quaife site in sevenoaks, as i'm often at the screwfix oposite. Great footage!
Glad you enjoyed it 👍
OK!
This is such a cool video.
I loved seeing this process.
I'm subscribing to you now PP
Thanks for the Sub mate. Welcome to the channel 👍
Great video, very informative. Thanks!
My pleasure 👍
great video bro very informative for those who havent had the chance to visit quaife
Excellent video! So interesting to see the machining and skill that goes into making these diffs. Far more complex than I imagined.Although you explained it really well I still can get my head round exactly how it works to deliver the appropriate amount of power to each driven wheel. I know my Caterham does not have LSD and i get wheelspin on the unloaded wheel , or inside wheel on tight bends. More Please!
Sorry, can, should read can`t!!!
I don't really get it either...witchcraft I tell thee 😂
Great video Pete👌👌👌👌👌👌👌👌👌👌 did learn a great deal about limited-slip diffs. Thanks, mate really appreciated. 👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍.
That is good to know 🙏
Only just recently heard about these products and this company, because I bought mk5 Golf GTI for a second car. And with all kinds of slippery conditions here in Finland, one of those diffs will certainly be going into my Golf :) With my "primary" vehicle, Jeep Grand Cherokee with 5.7 V8 hemi and Quadra Drive 2 I've got used to so much grip in all kinds of surfaces I really want my Golf to have as much grip as it can possibly get for a FWD car :D And so far I've only heard and read good reviews from Quaife,
Just wait til its on your mini.!! I have one on my westfield seven 👌👍. Cheers xx
It's on it and OMG !
Brilliant insight, Thanks!
👍
Fascinating stuff, nice one.
Cheers John 👍
Cool vid Pedro!!! I didn't know you were a CNC (cushy 'n' clean) guy originally. I've messed about with friction differentials on RC cars for decades, they're way less complex than geared diffs! But yes, an LSD is something that will make your car acceleryate faster and help you drive safer. Lowering a car won't make it noticeably faster, though you might save fuel, bigger wheels only make it slower and use more fuel (they're heavier and any increase in tyre circumference ups the gearing), so a limited slip diff is a really logical addition that almost no-one thinks about!
4 years at Uni studying Manufacturing Systems Engineering, although I ended up specialising in surface mount technology in the guided weapons industry followed by a move into the music industry making studio and concert sound desks !
Slow to catch up on this one, I've visited and met Michael but didn't get factory tour. That's a good little demo of how its works. So, -3 seconds a lap, we'll be watching.
Great video !!! I fitted a Quaife lsd to my bmw M135i great modification really made the car !!! Best mod by far 👍
Does it help with traction? Those cars can catch inexperienced drivers out
@@robinhosleftfoot yes great help with traction car used to spin out all the power on one wheel!!! Now it just grips and goes suspension upgrade greatly improved the car as well.
@@richardtrow2751 Cool, enjoy. Got more respect for that car now seen new M135i
After watching this I purchased one for my 2013 MX-5 Miata. WOW, major difference in feel. Rear end immediately felt more secure. Felt like 500 pounds were added in the trunk. Better take off and corners are a breeze.
Indeed 👍
I love it, very interesting car review... how a performance component of a car is made...
Cheers Luk, glad you enjoyed it 👍
Very Very interesting to see how this works... I have been looking to get this done to my F56 ...
Driving impression video coming soon but I can't believe the difference it has made. Very impressive 👍
Standard on my 2009 Championship White Type R. Makes the car! :)
I fitted one this year on my dear 306 S16 which I've had since 2003. It has had quite a lot of suspension upgrades, KW Variant 2 coilovers, Peugeot Sport GrpN wishbones, torsion bars, rear beam mountings and engine mounts. It has been fun to drive both on the track and on twisty roads - last year I fitted semi slicks on lightweight wheels and felt that they were a major upgrade.. well the diff I fitted this summer was the cherry on top of the cake. Of course - every upgrade supports each other but the diff made it like completely a different car.
Sounds like a great car 👌
it sure is for me and it is probably the only car I own which I am never going to sell. I dailydrive a mk2 Audi TT 3.2 which has some minor suspension upgrades (H&R springs and Powerflex black series bushes) but still when there is a trackday I will most likely take the S16 out rather than the TT which is easy to drive fast but lacks the thrill of a "Peugeot GTI" ;) My so called home track is Ahvenisto which is considered as the mini-Nürburgring of Finland and with such a small (ish) car I feel that I an make the most of both the track and the car. Still the car could use a few extra hp now that the suspension and drivetrain is in order :D (and the driver has learned somewhat to drive during the years)
Great video mate. Haven't seen anything like it. 👍
That is great to hear. Always want to do something a little diff-erent 😜😂
Awesome stuff Ped
Cheers Dan 👍
Great video Mr Ped!
Thanks Mr Ray 👍
Very interesting. And great job on your vid. If you get anymore chances to do more like this I’m sure they’ll be well received.
I'd love to do more vids like this. Glad you enjoyed it 👍
quaife wow thanks for the inside look
Glad you enjoyed it 👍
I had a focus mk2 st. I did some mods to it, power and chassis. But the most useful and effective mod was the quaife atb lsd. Totally transformed the car's cornering hability improving the traction. Night and day. In every fwd turbo car, this has to be standard from factory in my opinion. If the car doesn't come with one, you'll waste lots of power in the corners.
I agree 👍
I have liked LSD since the 90's, never thought it would make my gearbox work better.
LOL 😂
Superb, Really informative.
Glad you enjoyed it 👍
Fantastic video and great engineering company. I have a Quaife LSD in my Mk3 Focus RS.
Nice 👍
Hi Peter this has to be your best vlog yet. Very interesting, it's good to see how something that's hidden away is put together, it could be the start of an occasional series, what do you think. Educating your followers. .. Regards Simon.
So pleased you liked it. Wasn't sure if people would. I would love to do more of these 👍
I recently bought one for my mr2 and disassembled the housing to fit the speed ring gear. Once the housing is put back together are you supposed to be able to spin the gear inside? Mine does not spin using my fingers but i wanted to be sure thats how its suppose to be before putting it back in my car. Thanks for the help!
I second that a massively great video, thanks to Quaife and Lohen for giving us access to share the experience, I would like to see many more video's of this nature, how about logistics at VAG audi for the R8 or such like...when people see the engineering and design effort that goes into manufacturing something, it's a lot easier to ask them to part with their money. How many people realised that a LSD helps with safety and braking.. not just putting power down, but preventing a skid. This video really makes you stand out and that's important. We have all seen exhaust mods and engine ecu maps, for the more experienced viewer we already know changing tyres is more important it will make you faster..... long before you add extreme loads and temperature to components most owners don't even know exist. The trouble is, we all like to think our cars are unique and I have another 45 bhp... over a standard model.... again, with only a little driver tuition in a standard car, you will beat the mod driver every day...not to mention be a lot safer on the road for the rest of us... the general public are to eager, to right of speed as dangerous and yet many of these features when applied correctly are excellent safety features.
Great to hear you enjoyed this one Alan. I hope to do more of these as it was fascinating to make 👍
Maybe they can let you come back and do a separate piece on transmission gearbox... it must have been hard work filming in a factory with the noise level, but I think you got it right.
Top notch company and video once again ! I have heard of their diffs since I was a young lad and never understood the concept behind what went into them. So huge thanks for doing the vid !👍👋
That is exactly why I wanted to do the video. Great to hear is was useful 👍
Excellent film Peter, UK engineering at it's best... You should turn this format into a behind the scenes series of UK Automotive engineering companies?
I'm thinking of doing just that 👍
Excellent!!!
Cheers 👍
Another great video and very interesting finding out the manufacturing process of these diffs,being an aerospace cnc engineer myself i can relate to the manufacturing environment and i'm happy to have found out that quaife make a Lsd for my celica tsport. Now wheres my debit card😉
They make such a diff-erence 😜😂
Love it amazing what us humans can do 👍
Great video, British engineering at it's finest
Indeed 👍
I think they know exactly how long it takes to make each diff lol they just dont want to share that kind of stuff for public info and rightly so.Great engineering.👍
Probably 😜
Was there a Gleason Torsen similar to this? Had one years ago in the front differential of a four wheel drive truck and it worked very well.
Not sure, sorry 😪
I just installed a Wavetrac LSD and lightweight aluminum FW with stage 3 FX300 CLUTCH.
My mom told me to never even get close to LSD but I must say I'm more tempted than ever before 😁
This type doesn't make you see pink elephants 😜😂
Great video! Is there slight wheel scrubbing at low speed turns?
Not that I’ve noticed 👍
Small world!! I drive past the Otford HQ regularly on my way to work and the Gillingham factory is about 5 miles away from my house as the crow flies.
Finally an explanation i can understand thanksss
👍
Very interesting 👍
Cheers 👍
I know this is not a Diff and we dont have a mini, but we run a Quaife Sequential gearbox on our race car, fantastic bit of kit, Dave King at Quaife is a legend too, great video...#keepingitbritish #britishengineering #Quaife
Apologies for the repeat posts... (all deleted now) for some reason it looked like they didnt post... my bad
