Count me in for sure, 550/500 can't wait!

[1funV]

Sorry! meant 500f/550r Thanks.

Can anybody who is asking for 500 for the front and 550 for the rear please explain why??

My Z06 has the VBP Extreme Kit which is 850 for the front and 750 for the rear.

I have intrest in this for our CTS-V but don't understand why everybody wants the rear stiffer?

I would assume it's to dial in the understeer. Though our cars are pretty well balanced in terms of handling, virtually every car manufacturer will tune their cars with some amount of understeer, due to safety concerns and all. But the likes of those on this forum would most likely say nay to any amount of understeer, hence the further stiffening up of the rear suspension.

Any and all, feel free to intercede if I am incorrect in my assumptions. G'day den mait.

You can't compare springs rate (or spring rate increases) across cars.

The V comes with 400lbs springs front and rear. And GM has dialed-in some understeer. Running 500f/500r gives basically the same amount of understeer. To reduce understeer you increase rear spring rate (or decrease front spring rate). Running 500f/550r decreases understeer just a hair, making the handling extremely neutral... without any snap oversteer or nastiness.

These spring rates were chosen by GC after significant R&D (calculating wheel rates, measuring shock frequencies... see my BIG GC thread for more info)... and real world street and track testing.

Thanks, that is what I needed!

SOUNDS GOOD, keep us updated.

[DILLIGAF]

Why isn't GC posting yet?Mods?Are they supporting members yet,in the works?You would think they would want to get a list started and start taking some money from us.
