When he calls to order them, he can talk to the rep and tell him exactly what he wants (street, autox, roadrace, etc) and they'll help him choose the best spring rates. But careful, they sometimes get a bit impatient.

They also have kinda generic recommended spring rates for just all purpose street/nice handling/occational autoxing. I believe their recommended spring rates for my car were 380f/275r. A bit on the safe/understeer side, but probably much nicer than the average springs or coilovers around.
thanks so much for the information. when i install it on his car... do i have to worry about the preload... ? also, where would be the cheapest place to buy the GC? i've checked on GB but can't find anything. any suggestion of online shops?

with your setup... 350F/400R, does that give you more understeer or oversteer?

I've never seen a ground control retailer. As far as I know, you have to go straight to the source and buy 'em from ground control ($289 is the standard price). I'm not positive on that though. As far as Koni yellows, just keep an eye on GB and ebay, anything under $530 is a decent price, just wait for the best price you can find--I think mine were $515 shipped.

a higher rear spring rate will generally give you more oversteer , a higher front spring rate will generally give you more understeer (like from the factory)

too high of a rear spring rate can make things tricky on snow/ice/gravel though... if it will be primarily a street car, I'd stay on the safe side--although there are some folks around here that have rear spring rates of 600lbs+

damn... 600lbs. that is too much. i think i'll tell him to go with the same setup as yours, if not 350f/400r. thanks for the advise.

There are alot of things that can make your car oversteer/understeer. Playing with tire pressures, shock rebound and compression, sway bars, and springs.

This setup will make the car more neutral (getting rid of understeer). But I'm thinking of switching the springs around, to keep the car from diving under braking, and getting a larger rear sway bar.

Theres a cool idea. Do you have the stock SI sway bar?

The other nice thing about GC, is if you have the coilovers(perches), you can get replacement springs for $50/spring. Ive been thinking about getting a summer set and a winter set, but I'm far to poor for that now.

sweet, sway bars are definitely on our list of future mods. btw, are the 400lb GC listed as race springs or autocross or street?

They don't really classify it like that. You just tell them what handling and ride characteristics you want, and they help you choose the appropriate springs. So it all depends on what your friend wants from his suspension. btw what car does he have? (year and body type)

he has the same car as mine... except his is silver. it's a 2000 civic ex.

i just check on GC's site. it's $299 +$10 per springs when you buy that koni specific mount, which is about $339. damn that's pretty steep.
