I need to up my spring rates and am currently running Robispec'd KW V3 clubsports. Currently I am running 448lbs. F and 504 lbs. rear. I would like to jump up to 556 lbs/in F springs and 672 lbs/in rear springs. I don't think I'd like to go too much higher given the car is also my daily driver.

The delima is which springs to run. I have heard mixed things about Eibach, although they (Eibach) must be doing something right since so many racers use them. Hypercoil I haven't heard too much about and the same thing goes for KW. I currently have a set of 448 F and 504 R KWs on their now.

I am almost certain the KWs accept a 2 1/4 inch spring.

Any thoughts would be appreciated.

We have used (and continue to use) all three of those options and they are all great options. I think the paint quality is best on the Eibachs but to a certain point, a spring is a spring and you won't notice a difference between them as long as they are the same rate.

Thanks Dan. I was talking with Dave Mac over the weekend at the NE Divisional. We are both running the KWs but, he is using the Hypercoils and had said the Eibachs are "okay", hence my question.

Am I right on the diameter of the spring? I haven't measured them yet but, I figured you might know. Also the height? Dave mentioned I could get a set of either Eibachs or Hypercoils from you guys. Could you PM me a price?

Thanks

 

They're 60mm ID.

PMing you now.
