OK I had posted all the info you'd need for this thread previously, it's all about the spring rates PERIOD! Ground Control has a better sleeve design since you have just one lock that locks with an allen key as opposed to the Skunk2s with two perches, but ride for ride get some Ground Control 400 pound per square inch fronts for a civic and 300lb/in rears and compare to Skunk2 with the same spring rate you will not notice a difference unstil you have to adjust them and the perches are different. Me and technic1 explained this already, so everyone is posting biased bs without facts , thank you drive through!
