I thought i post a new thread since i'm stating a whole new kind of problem.

my friend installed Ground Controls coil-overs on his Civic Si about a month ago. Up to date, aside from the conventional twist and twang there is also excessive wheel-hops everytime a drop clutch launch is performed. (I'm being bland, a better way of describing it would be : THE CAR STOOD IN ONE PLACE FOR "AT LEAST" 1 SECOND WHILE ITS FRONT WHEELS ARE STOMPING UP AND DOWN IN AN OUTLANDISH/FRIGHTFUL MANNER.)

is this common for anyone else here?
