Hey guys I'm probably going to be getting some GC coilovers in the next month or so and I was curious as to what spring rates you would recommend. My car is a daily driver, although once I get my FI I hope to be taking i to the strip fairly often. I also plan to do some AutoX and possibll some road courses in the future, so I want to get spring rates that will compliment those things as well.

I really don't know all that much in terms of spring rates and such, so I was hoping for some good advice. Also I will only be dropping my car about 1.5" lower than stock, and most of the time not even that low. I will also be using KYB AGX, as I already own those.

TIA

 

If you're getting your coil-overs from Ground Control, call them up. Explain to them what you want in your suspension and what you are planning to do w/ your car. They will be able to tell you what you need and what will more than likely work the best for your situation. Tech support at Ground Control is top-notch, that's one of the highlighting facts about buying from them. If you get the suspension and feel it needs some tuning, buy additional springs (springs are only like $50.00). Ultimately, whatever feels the best for you will be your best combination; good luck.

 

Running KYB AGXs with a 1.5" drop using GCs, I wouldn't go with springs that are 50% stiffer than stock. This means 300f and 200r (or so).

If you can, spring for some Koni Yellows so you can get higher rates as well as drp the car more (if needed). The KYBs just can't take the abuse of stiff springs with a 1.5" drop.

And do what coquinn said...call up GC and talk to them. But they will only give you tech help once you supply thew with a CC number...

 

What kind of car will the GC's be installed on?

A friend just bought 300F 425R GC's for his hybrid 92 hatch (built for autocross). His suspension is finished off with koni yellow's, ST swaybars front and rear, and poly bushings throughout. I was surprised to find the ride quality was very streetable. His setup is a bit of a compromise because it's a street driven car. An "ideal" setup might be closer to 400F/600R, but that isn't really a streetable setup on a Civic (imo). The ratio between the front and rear spring rates is important. If you shoot for a 2/3 type of ratio, you should have a decent bit of oversteer. Plus, the front will stay planted better because the rear end won't squat much. For an Integra, the numbers are probably a bit higher since they're heavier.

 

thanks for the replies I'm going to give them a call, besides they are located like less then 5 miles from my house.
