Me To!!!!!!!
My 94 has 17" AR Sniper aluminum wheels with Michelin Pilot Sport A/S tires and it still shakes but not as bad. The SC had the Snipers and 1/2 worn Goodyears on it when I bought it. It shook bad then. So I replaced the upper A arms and the sway arm bushings when I bought it because it needed it. When I had the Michelins originally installed and DYNAMIC balanced (no weights on the outside of the rim - stick ons close to the outside and regular weights on the inside) it shook like a bitch all over. I was pissed having just spent $800 for tires. Then I took it to Tires Plus and had them DYNAMIC balance the tires with a Hunter 9000 balancer. This was the balancer that The Tire Rack (the internet tire company I got the tires from) recommended. It still shook. I took it back and they STATIC balanced (stick ons close to the outside of the rim) the tires. The front shake nearly disappeared although the car still had a slight irratating vibration. Then I took them to a brand new BJs that had brand new balancers and they both DYNAMIC and STATIC balanced them and the shake got worse. Soooooooo I went back to Tires Plus and had them STATIC balance them again on the Hunter 9000 and the front still shakes a little below 80 and a lot at 80+ MPH.
QUESTION: Does anyone have this shake problem with stock SC rims? From the posts it appears we all have larger aftermarket aluminum wheels. Could that be the problem? Does the wheel offset need to be exactly the same as the stock SC rims? Just some food for thought!
