I read every thread on this web sight and many others concerning wheel hop and saw suggestions from new shocks to something as simple as lowering. I was having a severe wheel hop problem with my 2003 Z06 especially on high traction surfaces and something had to be done.
Based on the things I read here is what I did and the order I did it.
1. Lowered the front and rear to the lowest possible settings using the stock Z06 bolts - Car looks much better but no improvement with the wheel hop problem.
2. Had thorough alignment done at GM dealer. Explained problem, but after alignment they said it needed very little change and was OK. Wheel hop problem not any better after alignment.
3. Replaced stock Z06 tires with 315/30/18 Michelin Pilot Sports - Better traction but wheel hop problem was still there.
4. Replaced rear upper and lower control arm bushings, rear sway bar bushings, and spring cushion bushings (The one just below the height adjustment nuts on the rear spring) with poly bushings - Wheel hop problem almost entirely gone now and barely noticeable using any launch method on any traction condition!
If I had this to do over again, I would skip everything else and just go ahead and do the poly bushing replacement first and be done with it.
The only disadvantage to poly bushings is a slightly stiffer ride in the rear and the need to occasionally lubricate the bushings to avoid any possibility of annoying squeaking. Please note that is best to have the rear end realigned after the bushings have been replaced about a week and they have settled in.
I hope this info helps someone on here because I would have done this as soon as I bought the car rather than worrying about it for a year before finding the real solution.
