I currently have H&R race springs, koni yellows, ITR rear sway, and I'm thinking of changing the springs. The rides a bit too harsh and too low. I was thinking of putting H&R sport springs in the front (sport are 275lb and race are 460lb) and use the race springs in the rear (350lb for race and 275lb for sport), I can even out the ride height because of the perch settings on the koni's. What do you think? Mostly driven on the street, only on the track 2-4 times a year, thanks.

 

Just fyi... the higher spring rates in the rear will promote oversteer, which is a good idea for autox type things. For daily driving im not so sure if you want to go with that setup. Im not sure if the spring rate is too harsh, but you might be prone to losing traction in the rear and that can translate to trouble for daily driving purposes.
