ok whats the stock spring rate for a ap1 and whats a good adgressive rate to rock thanks for the help

 

are these springs gonna go on the stock shocks?

 

Ya, depends on what shocks you run ... and what kind of oversteer/understeer bias you want to have.

imo, I wouldn't want to run anything over 8 or 9k unless you don't plan to drive the car much on the road. FYG, CR has 7k in the front and 4.5k in the back. Stock 03 AP1s have 4.2k around the corners, earlier AP1s have stiffer rears than fronts. Give or take some for those figures (I don't have them handy).

 

OEM:
00-01 - Fr: 218(3.9) - Rr: 291(5.2)
02-03 - Fr: 240(4.3) - Rr: 230(4.1) <<est.

I put this together a while ago in the S2000 modifications forum. Should answer some questions. Look in that forum for more good stuff.
