no matter what people said about this project, this is so sick. i love you guys
Criminally underrated channel.
Plastic can be gas permeable. If you really want to keep something for a long time, go the hipster mason jar route and vacuum seal it. A hole drilled in the lid with a shrader valve should work just fine.
Awesome video. I learned a few things.
2005 E46 M3 here.
Next project:
Fix drive shafts issues, bearing, guibo, and maybe the universal joint.
Need new bushings in subframe. So I just bought a used subframe with fresh OEM bushings already installed. They are OEM and correctly installed.
If I had the money I would get those purple bushings it to use. Those are the best POLYS I've ever seen. All right absolutely love the design. In the fact that they transmitted little-to-no NVH, makes them a real winner. I will have them installed sometime next year.
Even on the forums I don't think they know about these bushings.
I already have a beautiful set of Turner Motorsport rear camber arms.
I have very stiff polyurethane rear trailing arm bushings. I have TMS limiters put in, so I'm just going to install a set of stock OEM LEMFORDER RTABs. That setup is supposed to work quite well with the TMS limiters that are already installed.
I have 6 piston and 4 piston Brembo Gran Turismo brakes with Brembo floating rotors on all four corners.
I have titanium brake shields in front for the pads.
I have a set of racing pads by Cobalt Friction and I set of racing pads by Endless.
I did not like Poly on my front control arm bushings. FCABs.
I went back to stock LEMFORDERS.
The best way to add extra Caster is to have front camber plates that also adjust caster.
Adding full Caster is one of the best things I have ever done for the handling on my car.
There is a couple of tricks to prolong the can-life of your POR15, Rust Bullet etc... Replace the air inside the can with either propan gas from a small torch or argon from your welder before you close the lid. Clan the lid with tinner first so it opens easily next time. You can also mix in some thinner before you close the lid. It wont dry up for a very long time. Awesome build guys! Cheers!
Like the episodes this long, quite satisfying 😎
Hard to believe these guys only have 270k subs, should be 2.7M with the quality of content coming out!
I do my part. subscribe , notifications, and watch every vid from speed academy.
I'm a big fan of the SuperPro products.
Im loving this series. And those wheels, again, R GORGEOUS!
fun project guys, a trick I learned on the Miata and may work on the BMW for getting the axles in is to reverse the axle nut assuming the threads to all the way through and use it to leverage the axle in.
Big lesson to be learned here. Repairs, tires, and brake upgrades BEFORE adding power. So many people add power and never think about stopping, grip, chassis fatigue. Really enjoying this build so far. Makes me want to start another build myself!
Really like following this build, i just had mine done, and now has all poly bushings in the rear craddle and diff bushings, made a hugeeeee difference......its so worth it
I have one very important information for you. Never use a hard, non flexible bushing in the rear trailing arm. The rear trailing arm wants to make a 3D-movement while travelling up and down, cause it's also changing the camber while moving up and down. A non flexible bushing wants to prevent it from doing this. So the bushing is shifting the force to the mounting bracket and that braces it against the chassis (hope you understand what I mena, I'm German). It can tear out of the chassis through that. There are many cases of this failure on E36s and E46s which are used on the track and had these stiff bushings. Use unibal bushings or stiffer ones out of rubber.
Keep on the good work!
Wanted to write this also! You should never use poly on the E36/E46 RTAs. Use Uniball or rubber, but never poly.
I’ll be honest. I never watched any of these episodes because I was dreaming that you guys would swap in the v10 s85 …. Yet the amount of suspension work is nuts and I’ve been enjoying tremendously
This is what my e39 M5 needs and I will be doing complete read end over haul next year or later this year !
This is one of my fave channels, I'm always excited for new build videos! Thanks for the content, gents!
Excited to see the end of this series!
Love coming back to this channel, even after not watching it for a couple of months, when I stumble across one of your videos it's like I never left your channel, good stuff guys, keeep it up
This is my dream build, really enjoying this
Awesome!
thanks for being upfront
ive never left these types of video WANTING to rebuild a rear end haha
awesome! love the build guys!
Cheers from Argentina!
This project is becoming more and more awesome
I learned a trick for POR15 from an internet hot rod guy: Punch two small holes on opposite sides of the lid, and screw in some deck screws to seal it shut. When you need to paint, remove the screws, pour as much as you need into another container and then screw your screws back into the lid. The POR15 will harden around the screws and seal them shut.
This thing is going from mucky to minty real quick! Awesome job guys!
I really want to see yall build a c5 corvette for the track you can get base models for under 10k now
Z06's are barely more than that and are much more track ready.
c6 z06 would be 10x more awesome
@@Chilicharger665 tell me all about it? Its not the big of a difference between the base and Z I have a Z, but I do agree high mileage Z06s are steals
Been saying id love to see a c5Z track build!
Thanks for the tool recommendation. Just ordered the bushing removal tool :)
great episode guys. I love the level of detail on your channel. Most focus exclusively on the engine & performance mods whereas you guys show so much more. I learn something new each time and look forward to the next.
Great progress! Good on you for taking the extra time to get that rear subframe looking like new. Not long now!
Speed Academy rebuilding an E46 M3 subframe? I'm having deja vu! :P
Definitely one of the best channels on TH-cam!
Nice bearings F.A.G.
Jackie Ding crashed his A90 Supra. You guys should buy it and rebuild with widebody kit. Airbags deployed so track or drift car would make more sense than replacing $2000 work of airbags.
Unexpectedly getting hit right in the feels
I wonder if they come in a rainbow colored box
That ladder falling was God's way of saying no to the 2JZ. Boosted S54 would've been the grouse
All that effort and you guys didn’t clean the CV joint boots? My OCD is dying here 😂👏🏻
I'm really surprised you didn't replace the bushings in the rear differential cover after going to all that trouble to rebuild the rear suspension.
Todd Grzech Thats on purpose. Those bushings tend to transfer alot more NVH directly into the chassis we find so they were left alone.
You guys are awesome for doing what you do! So entertaining and super informative! Keep up the good work 💪
POR 15 a great product, but your complaint was mine in the 90s. The can just never seals well enough. Nothing changes, but the plus outweighs the negative.
Nice work guys, this is a sick build.
Great video! The only critique I have is after all that work with the axles you left the old, crusty, cv-boots on there.
Yeah...was wondering the same.
cool build
The Milwaukee m18 fuel tools are so good!
I Love this project and am inspired to do more for my E46 M3. Thanks.
Wow you have a nice car!
One of my favorite series 😁😁😁
That sand blaster is funny! Shooting it into the bin makes it all come straight back at you! Must have lost some skin there... :D
I hate what you have done to the interior, but i love what you are doing with the "body" and the suspension of this car. I do think that a 2jz is a good choice.
Best bet with POR is to put it in a glass container like a small jelly jar or glass baby food containers, the more you minimize the air in the container the slower it will cure... you are better off filling it to the very top and tossing the rest than putting it in a larger container with empty space. (obviously taller thinner containers minimize the air exposure and a flat Tupperware is probably the worth possible choice) Store it in a fridge and it will slow down the curing as well. I've also heard using two screws in the original can to make a pour hole and and air hole, and then using canned duster to displace the air before you reinstall the screws close it off but i have not verified this method.
Hell yeah. Looking forward to 2j shu tututus
These vids are amazing
at the dealer, even with brand new cars, the axles are also a pain in the ass to put them back in, the tolerances are just so tight so it makes it a pain to put them back into the hub.
Beautiful color, I don't think I've ever seen that color on an e46 in person
I'm going to toss my "internet opinion" in here. I like to use anti-seize on parts like the c-clip and the driveshaft splines. Even in a dry place like Las Vegas, it helps if you ever want to take those parts apart at some point. In a place like Canada and salt road areas, I can't imagine not using anti-seize on parts like that.
I was thinking the same exact thing when he was installing those clips.
Yeah but the standard silver antiseize sometimes makes it worse as over time the oil comes out of the solid and then it doesn't end well. I use the copper based stuff as I'm pretty sure you can use it with steel bolts into alloys without it rusting.
I use anti seize on everything. My brand is non galvanic. I live around salt air in Fort Lauderdale . Special Marine based formula.
Good stuff. Not copper or aluminum.
@@deplorabledave1048 where I work all the machines get washed with super saline ground water (up to 7 times earlier than the ocean) and copper based stuff has worked well. Then again I do have big rattle guns and breaker bars to get stuff off 😂
Coming together great!! Sucks about that damage on the car tho! Also I would be worried that aluminum suspension part will strip out and not have a good result. The cheaper aluminum honda ones are known for that to happen.
That poor old diff didn't get any love!! I'm curious as to why? Are they already quite strong?
Top notch A.
#notificationsquad. Loving this build!
you guys should look into puting 135i brakes on the e46 and you can use the csl rotors.
Great build !!! But one thing you missed was the reluctor rings on the driveshafts they'll throw up an abs code and drivability issues when they fail 👍🏻
For BMW brakes, especially e46s, Performance Friction Company make the best brake systems especially pads
Impacts also snap those bearing tool studs if you can't control the power
great vids guys!
Love the videos. Looking good!
the plastic did your sealing job in. the plastic doesn't stretch very well making wrinkles which creat leak paths. the original rubber would have been better
love the build!! Are you guys gonna do another 7 day race Vlog? that one was epic racing the FRS!
How about carbon fibre doors!? Don't see them done that often especially not done properly
I'm amazed you didn't just keep the standard engine and just supercharge it.
Ashish Patel doesnt make enough power
19:52 I would highly recommend replacing the portion of the right side brake line you see in this shot. probbalby a good idea to inspect al the lines since these look super crusty
Mark Proper yeah those lines are just dangerous
heh you should have seen the brake lines on my 88 mr2
Great info thanks
How big is that front rotor? It looks a little small and so do the calipers. I ask because I’m going to upgrade to 6 piston calipers on my car and it might be overkill for street use only.
Shouldve done the parts cleaner then the media sprayer.
Bushing/ball joint thing is called Johnny Joint
That diff is not completely sealed. It has weep holes on the sides and the rear diff cover. Hope the parts cleaner didn't get through. At the same time, why not just put on new output seals and a new diff cover for this super car killer build. I also hope you are using BMW's upgraded new diff bolts (23001222891) so they don't back out.
Did they rebuild the diff at all... change the fluids, clutches, check or replace the gears?
do a cost analysis video where u cover the parts and the total price of the car (how much was spent on it total)
What are your plans for the bushings on the diff cover? They do fail if too old. Ask me how I know.
With por15 I guess oxygen is a catalyst I think if you purged it with argon it would not go off. Think I saw that somewhere else.
I pour my POR 15 in a Mason jar after the initial opening. Just have to clean the top of the jar and the lid really well before closing it up each time.
Please put a bmw megatron engine in a Mark 3 Toyota Supra
Going to be a nice bmw
Dave … Dorman ball joints? Come on man … Lemforder!
Call Dan at Precision Dent. Crease be gone.
I use that same copper nickel brake line on all my customers cars!
If the brake lines looked that bad don't you think it would be a good idea to replace all the lines front to back?
I know all about the emergency brake cables. I didn't know they were so reasonably priced. I used the Doorman number and found them on Amazon for $20 apiece shipped.
I did not know about the brake lines near the subframe. I hope we don't have to redo those like you guys did.
I will wire brush and soak in Kroil.
Rally car build off should be done! Then a trip to dirt fish to compete!
Like butter, how many times can you guys say that in one episode 😂
Try storing the por15 in a glass mason jar.
plastic doesn't completely seal air. you can get a new paint can from a paint store or use a glass mason gar.
22:30 "shit hits hard" lol
I love that build, looks porm for me haha
0:49 cross
You guys have rebuilt like 100 subframes and I’m just looking at my 240 wondering when I’m gonna pull the trigger on a set of collars.😂
I said on a previous video the drive shafts are a tight fit and are suppose to be pulled into hub using a special tool
Neil Johnson we should’ve read that comment!
Some companies offer graphite infused poly bushings which squeak less than poly bushings without. They just don't look fancy.
With those brake lines, copper nickel, and their malleability, does it hold up to pressures of braking on street and track? Those seem to be the best option if they don’t expand under pressure like plastic pexpipe does for residential homes.
Gretchen Roper Nickel Copper brake lines are the best thing since sliced bread. I’ve run them a couple race cars and they hold up great and make re-lining a car a joy. They are still a hard line and more rigid than any braided flex line.
Ahh😥 I wanted then to open up the diff and have a look at the gears..
Plastic is too permeable for that type of coating. Depending on the chemistry it may even cure by way of moisture which can seep through the micropores of the plastic. Old mason jars (left ofer from your favourite PC brand pasta sauce) work best.
alex choi could have used those studs on his M2...lol
he only buys wish dot com wheel studs
lmao did he snap wheel bolts or something? smh but I run wheel bolts in my 550awhp 535xi and have had no problems, but I have replaced them like 3 times with every major wheel or brake change/upgrade so maybe that has something to do with it lol deffo getting press in ones when I do subframe bushings tho
@@von... watch emilia hartfords second last video, she details her crashing alex choi's M2 while drifting.. you see the wheel rolling past her with a clueless look like wtf just happened
Everything new and refreshed but those axle boots look crummy as hell. Hopefully they don't fail.
RivalBro OE axles are known to be the best and rarely fail. Aftermarket units on the other hand are known for their issues. Didnt want to spend $800/each just to make them look pretty.
That metal treatment is NOT designed as a final coat. Not all. It MUST be top coated. It comes in a KIT usually with a top coat included.
Redish in England uses it. I watched a separate video on how to best use that brand of metal prep.
I went to the SuperPro Website you have linked but I couldnt see where to order their parts from, as I am in Canada too. Any info regarding where I could purchase their bushings would be great.
Nice job guys glad to see my clutch pedal in there, did you power coat that v brace as Well?
Makes for a perfect time for carbon fibre doors 😏
