<----cheap ebay coilovers on my ride. rides exactly the same as my boy's rex equipped with skunk2. only difference is the saw from the struts thats all.

 

i have always used skunk2 because they are a little stiffer than ground control, allowing a better launch... the ground controls are more for touring or autocross... from my experience, i have found that the skunk2s ride a little stiffer than the ground controls... it all depends on what you are going for, a better launch at the track, or better handling...
