Im gonna add coil-overs for adjustable ride height (tires rubbin fenders = smoke ) do you guys think i should go for a springs with a higher rate than my neuspeed race springs? if so how high should i go? the car is NOT daily driven but it IS a street car (autox/hpde/panty dropper)...suspension is stiff now but it doesn't bother me.

 

What are your neuspeed race springs rated at? Or was it part of a sport package where that may not be listed?

If you're still using it on the street, you probably won't want it too stiff. Besides, your struts/shocks may not be able to handle very high spring rates.

I was just reading another post about springs rates and shock valving...i guess my next question is what is the maximum rate i can run with stock koni yellows?

 

the common thought that I have heard is that koni's will "handle" up to 600 lb/in springs
