i have a 97 civic coupe. im buying gc/koni's. my car is a daily driver, and i was wondering what spring rates i should get. they thmotorsports recommented 350 in the front and 380 in the rear. i always saw in here the softer rates go in the back. he told me the stiffer ones do so the car can turn better. WHAT RATES SHOULD I GET?? i plan on droppin my car a finger cap between tire and fender maybe alil lower.

Daily driver that won't see track time?

400 - 500 front
300 - 400 rear

The rear rate will determine more of the ride quality. Yes, stiffer in the rear can promote oversteer (or reduce understeer really), but that isn't something a street car needs (or even wants in many circumstances).

Go on the stiffer end if you plan to lower to flushed tires. Softer if you'll stay higher than that.

Can someone please explain why the rear rate determines ride quality?

I keep reading about it but a reason is never given.

Thanks!

Because the rear end is lighter and will bounce when you hit bumps especially if you have stiff rear springs..
