Recommended Ride Height for FC

I'm autocrossing my 89 GXL in STS2, and wanted to know if there is a recommended ride height. I have a set of ride height adjustable coilovers with spring rates ~450lb/in front and ~335lb/in rear, and I'm running 17x7.5 wheels with 225/45/17 tires.

Do you have camber/caster plates in front and an adjustable camber link in the rear?

Unless you have scales, take it to a professional shop and have a full setup done. It needs to be corner weighted. If there are no restrictions in your rules, set it as low as possible while still maintaining clearance during suspension travel and without running out of shock. I'll assume you have camber plates/link as that is a must.

Yes, I have adjustable camber plates in the front, and an adjustable sublink in the rear. I also have access to a set of scales. Rules allow lowering the car. I can get my car very low without suspension travel issues, just wanted to make sure that by lowering it this low I wasn't adversely affecting anything.

ITS cars can't go lower than 5" from the lowest point on the rocker and most take it to this point. I doubt you'll be able to get any lower than that anyways.

Probably not with 225/45/17 wheels.

Run it high enough to clear curbs... that's all you need for autocrossing a street car.
