I was looking at getting Ground Controls on my MY99 GC8. They'll sit on KYB AGX shocks. I'm wondering if anyone has any insight into:

- How are the spring rates/lengths that Ground Control recommends? I've heard that their suggested spring lengths are too short e.g. on their AE92 kit.

- How's the ride and feel? This car is a daily driver. Any significant clunks or other noises?

- How was the install? Any cutting/welding involved?

Other info: Car has F/R strut tower braces but is otherwise stock. Ride and performance are important (although sadly mutually exclusive :), looks are nice but not the ultimate goal.

Thanks for any help.

 

Send Kostamojen a PM. He as coilovers on AGXs on his 95 L, which is mechanically the same as your 99.

 

Im running on I believe 8 inch springs with ~250 front and ~200 rear spring rates. Its very stiff, and I have to keep the AGX's up a bit in order to prevent spring rebound.

I have no idea bout the install, cause im the 3rd owner of this setup I just got the whole thing together and installed it.
