Our "track car" is actually one hell of a nice ride for the street with the out of the box KW spring rates. We haven't changed them yet. |

My past experience with progressive springs was that they gave a very uneasy feeling on initial turn-in. That may have been an application problem, but I've been wary of them regardless. Any sense of that with the V2/3s?

Turn in is excellent on our V3 car. We're running the "stock" KW springs. The suspension tuning we've done has got the car feeling great now. We could tweak some more but right now the car is probably a 9/10 with the setup that's currently on there.
Part of what we've done is run lots of pre-load on our front progressive springs. I don't really have a spring rate to give you since they are progressive, but they are just about perfect for spirited street driving. Just a tiny bit soft for agressive track driving on street tires. On R-comps you would want to bump up those rates even more. |

FWIW, I am running a 350 lb/in front and 900 lb/in rear spring but not with stock bushings. This means the wheel spring rate are almost the same. Orb |

You'll only find 4 adjustments on even the higest of the high end dampers. 1. High speed compression 2. low speed compression 3. high speed rebound 4. low speed rebound |

Another data point:
Call was kind enough to let me take his Cross equipped car out for a drive last night, and I came away impressed. I won't say that it rides "better" than stock, since that means different things to different people. I will say that the car feels rock solid, with no "bob and weave" motion. It is the way I think an "M-Tuned" suspension ought to feel. I would have no problem using this setup on my daily driver. The only downside I noted is that the extra stability encourages even more "super-legal" behavior! Thanks again, Call. Brian |

Brian, glad to meet you. I sure hope you can meet up with us sometime over on the Dragon or maybe on your next trip to Road Atlanta.
And, I hope no one else trashed their cars Sunday at RA after hearing what happen to a few M3's playing with the wall on Saturday. Sounds like the 80% guidelines must have been ignored a little with those wet tracks Call

I just sold my Evo RS that had Ohlins Flags on some crazy spring rates for STU. It is truely a car capable of winning STU at Nationals. I PAX'd #1 at the DC Pro Solo in it this past June and won STU. I think the 135i with Ohlins, AST's or Motons could do the same.
