Well that all depends on the type of coils and how your setup is. True coilovers will get you the best ride you can get. Closest to stock right. But say you got some cheap ass coilovers on ebay. Your ride will be so harsh that you never want to drive again. Or say for your GC coilovers....you can add koni yellows to them, and supposedly they will ride really well. I know a guy that has skunk 2 coilovers and he says the ride is extremely harsh. But he also doesn't have any aftermarket shocks, so that could also be the problem. It all depends on setup.
