Finally, an actual, legitimate long term review of a product, not just "I feel qualified to comment on long term use and reliability because I have owned this for 6 months." Thank you!!! I've had KW in the past on a couple of cars but really didn't want to spend almost $3500 on them (after tax and shipping) for my 540i. This has (almost guaranteed) changed my mind.
One of the best reviews I have seen for a car part ever. The fact there is no corrosion on the coilovers is amazingly impressive. Great informative video.
Yeah, I always read stuff like that "unlimited lifespan" or anything that is touted as _____-proof with a healthy dose of skepticism, but in this case, it seems as legit as I could test and observe.
I've had my KW V2 for almost 20 years and they are good as new. V3 was not available for my model at the time. Incredible quality, well worth the 1,300 Euros I paid back then. It completely transforms the car's road behavior.
I honestly expected worse but aside from the one leak, I couldn't really find much else wrong. Most OE spring/dampers don't last this long with heavy use...
@@LapoftheWorld The neat dust shield probably helper alot, leaky piston seals is pretty typical with normal coil over kits. But most kits have pretty much no dust and grime protection
Yeah, the super short version would be to check the adjustment points periodically for leaks and inspect the lower bushings every season but otherwise send it.
I just ordered a set of KW V3 for my 370z so naturally, while I'm waiting for them to arrive, I'm now looking at various reviews to justify my purchase :) You did an excellent job of reviewing these and I'm really happy to see that my purchase was probably really good. Can't wait to put them on the car and test them! Did I see well, did that NSX do 305.000 miles? Wow!! That's so impressive and so good to see such a beautiful car being driven as it was meant to. Hope you continue to have it for many many more years and miles.
🙌 Thanks for the kind words! The NSX is now at 321,000 and the new set of KWs is still just like new. Hopefully your luck with them will be as good as mine.
@rideepicdriveepic I'm going to be ordering the kw v3's for my 08 g37s coupe rwd 6mt. I have the v1's now but going for way more power and more aggressive driving, so I need a different version of coilover. I haven't seen too many g's or z's with v3's so that's a plus.
I have a 370z sport pkg 6MT with a significantly lightened unsprung mass and stiffer anti-roll bars. The car handles very well but I now want to corner balance it and optimize the damping on both compression and extension for body pitch and roll and for wheel dynamics. The KW V3 is obviously a very good quality damper and is available for my car but it is only a two-way, having only low-speed compression and extension but no high-speed damping adjustment. I would need to get a KW V4 but it is not available for my car. I'm looking at probably getting a set of Feal 3-way coil overs for my Z, the only drawback being their higher cost.
Definitely helps remember where you left them settings-wise without having to pull out the log-book or dig through the archives for installation notes.
Hi Richard, great review. Thanks for taking the time. I’m considering a set of Street Comfort KWs for my 2016 BMW 640D Gran Coupe. It sounds like they will do the job. Thanks again
@youtuber-cc8sx no I actually ended up going for the V1 and not the V3 as I wasn’t planning on taking the car on track so I thought it was pretty pointless to spend money over £1000 more, the V1s are incredible though so I’d highly recommend, unless you’re planning to track the car then I’d say go for the V3s👍
One explanation would be that monotube gives generally a harsher ride. And if you have only one car that you daily drive, and occasionally have some track days with it, I guess you wouldn't want to go bouncing around!😊
I'd be curious to see how the rebuild older model stacks up to the new models. Will you swap them out without concern if one of the new ones has a failure?
I'll be curious how the rebuild process will go, but that's the idea is that I'll have the re-built ones ready to go back on in case any of the new ones start to have an issue. Zero down-time etc. which could be logistically important if we do something more ambitious travel-wise in the future. I think the real tell-tale will be how the new ones hold up compared to the old. Is what they're making now just as resilient.
I’m returning to this video after my current set on my e36 m3 had its swaybar mount ovaled out due to a loosening nut (my fault) on track. Really struggling with getting these or clubsports or mcs. This it a dedicated track car, but I really don’t have the seat time to justify anything past v3’s. Currently have a cheap set that came with the car.
That's where I landed with getting the replacement set. I'm sure someone could potentially get more/better balance out of the clubsports, but I don't have a sufficiently calibrated butt to get the most out of them, and I'm an order of magnitude of subscribers short of being able to afford my own race engineer, lol.
@@LapoftheWorld I hope you get there one day! You’re an inspiration and a great source of knowledge and experience. Glad to have your time responding to my comment on an old video. Have a great day. ✌️
Did these ever get rebuilt or serviced during the 95,000 miles?? I've been kicking around the idea of buying KW DDCs for my F22 M240i. KW recommends a service every 40k or so IIRC, which gets pretty expensive over the life of the shock.
Unsure about service intervals across their whole damper ecosystem, but I didn't touch these (other than adjusting them here and there) during the "test" interval here.
I watched your installation vid first and found it very helpful this one as well. I'm replacing the stock suspension on my 97. I know long over due. I'm not to concerned how long the new coilovers will last, let's just say I hope I last as long as they probably will. My only concern is ride quality. I don't track the car but will want it to feel a bit aggressive for when I take it out for spirited but legal drives in North Georgia.
At least at my current age and spine condition, I feel like you can get close to the best of both worlds within the adjustment range. I'm a "set it and forget it" person so I have it just a smidge softer that probably what's ideal for track use, and just leave it there. They're perfectly fine on all but the worst roads, and still have the body well under control for track use. Again, my basis of comparison is admittedly not auto-journalist-broad with respect to what's possible, but I know "comfortable" when I feel it 😁
I shared some baseline settings in the install video I published last week. I hope to hit up an autocross soon-ish as a test/validation setting so may cover it again there.
I have 12 y.o. KW-V1s on my 2008 BMW 335xi. Bump stops and dust shields blew off after too many potholes 8 years ago. Threw on the OEM bump stops - starting to feel harsh over small bumps so I am exploring my options. Any suggestions?
If you bought them new, you could look at the warranty terms. They're pretty generous albeit void with track use and some other stipulations. From talking to my damper expert here the harshness is probably just the oil degradation (assuming no leaks) probably exacerbated by cold weather. As for non-KW options for a bimmer, I'd imagine the world is your oyster between Bilstein, Ohlins, etc. I don't have any 1st hand experience there, but maybe others will chime in.
How responsive would you say the settings can be adjusted for daily driving on unpredictable roads like Los Angeles? I bought my M2 that came with the AST 5300 and it’s still pretty stiff on the lowest setting. I want to change it out but Bilstein b6 is in back order until March and I don’t know what else to get. Budget isn’t a concern. Just want something like stock OEM suspension but better
I'm sure the damping may be different for different applications but at least on their NSX versions you can dial them pretty soft. Maybe not quite as cushy as OE, but I've driven on some pretty jank roads and didn't feel like I needed new kidneys.
It seems like the newer ones aren’t built like your old one was. Lots of failures with the KW V3 for the 2020+ Supras, specifically struts shafts breaking away from the strut body.
Wow. I guess "ymmv" is universal. Still for this application at least it's so far so good after a few thousand miles and 3 events on the new set. I'll definitely report anything that does crop up. This was in no way sponsored so it's not as if I owe KW anything at this point.
@@nineteen76 I had one that seemed to have lost height but the other three appeared fine. I couldn't tell if it was too short to start with, or actually sagged (given the others were identical to the springs on the new set)
@@LapoftheWorld I have found I had to keep adjusting the coilover perches over time to maintain ride height. Perhaps different spring supplier for different cars. KW don't make their own springs I believe. I've recently converted my V3 to linear spring rate using swift springs and must say it has improved the ride quality and handling. Good to know from your test that their dampers are good quality.
@@nineteen76 Using Swift springs has been a common approach with the NSX community where folks want to change rates on all four. I was just doing the pair so bought the slightly stiffer fronts from KW. The 'stock' KW springs for the NSX were already linear, but that's definitely the way to go for performance.
Great review! I'm starting to feel the effects of my stiff Quantum suspension so I bought the NSX-S suspension. How do these compare to the S suspension?
So I've never ridden in an NSX with S/Zanardi suspension. I'm familiar with stock USDM suspension which is downright cushy, and KWs (outside of other cars entirely). My educated guess is they'd still be a bit stiffer than than the S suspension, but with the KWs on the 343# springs that they come with you can dial them pretty soft while still maintaining good damping control. They won't get to full rolling-sofa, but with the stiff-leaning adjustments they recommend they still don't kill you on bad roads.
@@LapoftheWorld so close to home that I can't dare to criticize it! I am going to make the trek north to Brainerd for a track day this summer though too.
Rears are the "stock" V3 rates, but I went stiffer in the front to mirror NSX-R ratio. You just need to know the correct length and diameter and you can order from KW, Swift, whoever. Worth noting that it does void the warranty (or did per my literature) but track use does that anyway so it made no difference to me. It wasn't a drastic change and the valving seems to handle it fine.
Oh, I've thoroughly voided the warranty between the track use and up-rated front springs. I'll fill out the form, but I fully expect to pay for the rebuild. If something else happens I'll report back. The return/rebuild process might be worth a video for those curious about how that works.
@@Sleetui I do plan to document the process. I've had some other priorities but the old ones are stripped and in the box for when I have time in a month or two to deal with the paperwork and logistics.
Hopefully someone else can respond who has experience with both. Not sure I've heard anything bad about JRZ, but I haven't driven on their stuff to have an opinion.
I can't profess that KW is "the best" thing out there as I don't have experience with enough of a sample size, but I don't think you can go too wrong with them given what I have seen first hand.
These are nice but I just cant justify the price at 3k they cost 3x as much as other brands and for that price you could get a fairly decent used car...
So a crappy suspension maker is dissing the KW (probably best suspension brand in the world) most famous product the V3 by saying that "it's not bad"? Wtf 😂😂 what comes to my mind is that time Conor Mccgregor said "who the fook is that guy?" 😂 unbeliveable
No diss, you just have to know the type. I take, "Not bad", from a guy who builds/tunes race shocks for a dozen late model teams (Ohlins, Penske, etc.) as a low key compliment for any off-the-shelf product. He'd definitely seen much newer shock in worse states of wear.
Thanks for the data point. If you don't mind, were they V3 or a different model? Also, are you in the US? KW USA does rebuild these dampers. I'll update that process as well once I've sent my take-offs in. I wonder if available services may differ by model or location?
