need help, front end slight wheel bouncing
I have 2010 Grand Sport w/750WHP... getting slight wheel vibrations at 70 mph +. I already ground force balanced the wheels, replaced air dam, and chin spoiler as there was a very slight gap between spoiler and front clip. Looking for suggestions on what is causing this. Vehicle has new front tires 8000 miles ago and is highly maintained . has had two alignments in the last 3 years. Has 38k miles on it . Driven 4000-5000 miles per year.

Have you checked to see if the tire is round? I had a similar issue and when I raised the tire and spun it with a pointer set close to the tread I found the tire was out of round. New tire was installed and problem solved. Also the problem did not show up until i had about 3000 miles on the tires. Good luck

That was going to be my next question just like H8 mondays........did you check to see if a tire was out of round? Happened to me on my Genesis. Firestone tires, which I will never buy again. Not only were they noisy, but also had one tire out of round. Let us know what happens.
