Yah, agreed, most likely a 8k spring which is about 450lbs. That is just a number off the top of my head. Don't quote me on that.

Ah...that's it...8k.

8x55.88=447

Are all four springs that rate?

My old skunk2 coilovers were 447F/335R. 8K/6K

and how does that ride?

EDIT: my fronts are 559 and rear is 447.. i think, are my springs reversed?</TD></TR></TABLE>

So you have 10kF/8kR. That is a really stiff setup for street/daily driving. My old Skunk2 setup was 8k/6k = 447F/335R with KYB AGX shocks...and it was a tad rough.

But now with my Koni/GC setup...450F/400R...the shocks actually dampen the springs so my ride is a lot nicer.

It's typical to have the higher rate in the front due to the increased weight of the engine up there. Road Racers and Autocrossers tend to use the higher rate in the rear for better rotation. It's best to stay with a higher rate in the front if you're not racing.

Them stock shocks are never gonna be able to dampen them stiff springs. Off the shelf Koni Yellows are rated up to 600lbs before they need to be re-valved to accommodate a stiffer springrate.

Gabe may I ask why you run higher rates in the front when you do quite a bit of auto-x? Or does the bar make up for it?

I wanted the car to be neutral as possible but still have some oversteer when I need it. Anybody that drives my car at a solo event is always very happy with how nimble it is.

Is the overteer annoying or can you control it most of the time? I was thinking of a setup similar to yours.
