I got GC's with some really stiff springs, and i want to know how the ride is with Omniman's slip-over coilovers, does anyone have those? i cant compare the numbers because my springs dont have any. and your quick opinion, koni/groundcontrol VS omniman fullcoilover?

 

a full coil-over is better than a sleeve...BUT...sleeves can and will get the job done.

Those Omniman kits are probably pretty damn close to a GC/Koni setup being that, didn't he used to work for Ground Control?

Anyways...if your springs are 450lb or higher, expect a pretty rough ride, depending on your street surfaces of course.
