Kw V3 VS. KW CS

1cleanm3 · 04-28-2011, 11:07 PM

Hello my track junkies!

Does anyone have first hand experience between the two? What makes the CS coilovers a better system overall? I would like to possibly go 1.8" low in front and 1.8" in rear or so. Is it worth the change? I want to run the cs with rd sway bars.

Thx!

If looking for just a drop - the V3s are just fine.

If you serious about tracking your M3, get the ClubSports.

If you are going that low you i don't think a more track oriented coilover like the Clubsport will benefit you. There is a certain point when it just throws off the geometry of the suspension. Even if the coil can go that low it wont perform as well as if it was lowered 1.2". You are taking away from the full stroke of the shock and not letting it perform at its best. Some suspension guys can probably chime in on this. I don't know if the V3 you have can go that low but if thats all you are worried about then i would not get the CS.

I think 1.8" is too low for either system to work optimally for track use. One of the major differences is that the CS runs linear springs, compared to a progressive spring.

And the CS has camber adjustment, and I don't think the V3 does.

You're not going to the track, right? If you are, a 1.8" drop will make the handling diabolical - it won't matter what dampers you get because suspension will be sitting on the bump stops and not moving. On the street it will be dangerous and uncomfortable, but on the track I'd go with "suicidal" to describe the handling.

There's many Japanese suspensions that allow you to drop as low as you want. Don't waste money on Kw CS.

STALKER · 04-29-2011, 08:19 PM

OP, are you looking for a DD and track set up?
Little confused on your intended purpose?

How are the V3s at the track?

Very balanced shocks. Comfortable for DD, and good for light track use too. It's good improve over stockers, but still far from superb.
Since I'm planing to give the M3 to my gf, I would probably keep the V3. Otherwise, I would get either Moton or JRZ in a heartbeat.

V3s that come from the factory have springs that are too soft for serious track use. I dont remember the spring rate but i know that its not much higher than stock ones. I have v3 coils on my 135i and was not happy with their performance on the track. Too much body roll. There is Swift conversion kit available that comes with linear springs and thrust sheets. The good thing about this kit is you can choose any spring rate you want and they are linear that are more appropriate for the track. Thrust sheets allow the spring to smoothly rotate around the perch during compression. This will enable the load of the spring to be more evenly distributed. I tested this set up a few days ago at WGI and was very impressed.

Hey guys thanks for the comments. Im looking for a car I can drive on the roads (my car is not a daily driver) when intended, and enjoy my time on the track. I will track about 5 times a year or so starting this summer.

Ive had a e46 m3 with JIC coils, and that suspension was crazy!
