This is still primarily a street car for me..

Sounds like a safe bet!

Wow, crapping all over those m performance coils! For this thread, I thought the m coils are made by kw, so there shouldn't be any material difference, other than the BMW set likely to be cheaper!
If you're in the Ohlins or Moton league, you're going to be spending double the $1900 you can get the BMW set for. And then you need to find a place for reservoirs. And then deal with rebuilding the shocks regularly. If you want to play, you've got to pay! Hope you have the full cage and racing harnesses to go with!

No fucking shit right? It's a never ending slippery slope and an incurable disease.

I might be the only one not in the Ohlins camp but after owning them on 3 previous cars I'm not the biggest fan. Don't get me wrong, the quality of Ohlins is amazing and you can definitely see where your money is going. But my biggest complaint is that they are too stiff for street use, even at the softest setting. And then when you do get them to the track, the Ohlins are way too bouncy. Personally if I'm going to go with a steerable coilover with an occasional track day I would look into KW's or the M performance ones. If you want a real track capable coilover then go with JRZ's or MCS.

To stay on topic and address the OPs question, the only things I can comment on regarding the differences are the following:

KW:
Front spring is narrower allowing better clearances if you intend to either run camber plates or larger tires.
Rear spring is 9.25 inches

MP coilovers:
Rear springs are 10 inches and bottomed out with approximately "two finger gap". I measured the spring myself.

The shock body and coil sleeves are built off the exact same hardware. Im not sure if the shock valving is the same.

With that said, if they are both the same price, I'd go with the KW just because there is a "better" range of height adjustment and there is hard data such as spring rates and heights. I contacted KW and BMWNA and they have no technical data on the MP coilovers. If you find a killer deal for MP, new coil springs are about $50 a piece and are easily swappable to achieve a lower ride height.

I'm not searching prices, but I'd love to hear if the KW V3s are less than $1900 a set.

[bernstem]

I'm seeing the KW V3 at ~3k USD from multiple sources. I would be surprised if you can find them at 1/3 off that.

Thanks for this. Helpful!

Are we comparing apples to apples?

Other than the Olins which have a smaller diameter spring the M Performance, KW V2 (except rears), KW V3 and Dinan HAS have similar diameter springs.

[Danne_485]

Any more news on this? I have ordered an M2 and would like to know which coilovers to go for.

Any reviews on how they ride and how’s the adjustability?

For the adjustability - on the softer side, it felt smoother than stock dampening; and on the very stiff side, a little bit too stiff for the bumpier tracks we have out here. i had to turn down the stiffness around 2-3 clicks to keep the rear end from hopping around while braking. the GC camber plates really help w/ the tire wear on track and turn-in became more precise. overall the V3 w/ GC plates are a good entry-level track suspension. it's overkill for strictly highway/daily grind use, but will shine on the weekends in the canyons and b-roads, w/ a few track days sprinkled in between. track rats will probably want something w/ more adjustability/stiffness though. But for those who daily drive their cars and want to ease into learning how damper adjustments will affect the balance of the car at the limit, this is a great setup.

when i upgrade to the M2C, i'm going to go w/ AST w/ a little stiffer spring rate due to increased weight, so i'm selling my V3's + Camber plates for $1800+shipping.

I actually pulled the trigger on kw clubsport for mine to pair it with stancepart air cups

Thanks For the review AL.

I picked up the M perf coils but I am debating between going with camber plates. I’m mostly DD with a canyon cruise maybe once every month or two. I see most people saying camber plates only help tire wear on track, not so much for DD. I was curious of this because I do have premature wear on my stock MPSS while the middle of my tire still had a good amount of tread, I would love to even out the wear more..and is there a reason you chose GC over the other brands such as vorschlag?

Thanks!

if you are mainly driving around town, additional negative camber will only make premature wear worse. i brought in my car to get track alignment, and at the minimum setting of the plates, i was pretty close to -0.5 degrees with my drop before dialing in additional negative camber. i went with GC because i never saw issues with them on cars i installed them on back when i worked at a shop.

[PLF69]

Ultra, when you say the wear will be worst with camber plates only driving on the street, you mean the interior of the tire will wear faster like the exterior does when your stock ?

[K9GunSlinger]

^ so essentially getting camber plates will do nothing for me as I only DR and canyon a little bit, as far as better tire wear goes (more even wear, less wear on inside/outside)

i haven't driven long enough on stock suspension to notice any wear on the outside. however, have you tried getting an alignment done on the factory parts? i know people who track their cars without camber plates that get the outsides eaten up, but i'm unfamiliar w/ people who just daily drive the cars having bad outside wear. i think an alignment shop should be able to dial in a slight negative camber to fix that. which tires did you have?

i guess since i was addressing K9GunSlinger i was assuming the coilovers would be lower than stock, which typically introduces some negative camber. the wear on my PSS was pretty much mostly inside.

[18EM2]

I'm thinking the V3's are the best all around coilovers from what you're saying so I've decided to get them. Unfortunately they're back ordered it seems so I'll need to wait until that gets resolved.

My next question is what tires and spacer sizes? I'll keep the stock wheels for now but I will switch to the PS4S. I'm thinking of going with 255/30 & 295/30 with a 10mm spacer up front. Does this sound like a good setup? I'm open to other recommendations and input.

Thanks

I ended up going with the M Perf coils. Tischer BMW had a killer deal, Brand new M Perf coils but there was cosmetic damage (some scratches on the springs of the coils) got em for 1500 OTD shipped including the hardware kit (80 bucks). From my research the M perf coils are just rebranded KW V3, with some spec changes mainly that the KW V3 allows you a wider range of lowering. which for me i want to keep my car at stock height, maybe a LITTLE bit lower so i didn't care about that. so if these are really just rebranded KW V3, and you dont care about going super low, i would hit up Brian Keller at BMW Sun Motors, he can you you the M perf coils for about 1950 OTD Shipped i believe. cheapest i could find the KWV3s for were like..2150 i think.
