Maybe you can help me out here. Do you get any vibration with the Mustang rims on your car? I've had mine balanced twice and I have just a slight vibration above ~50mph. It's not horrible, but I'd like to get it smoothed out. I don't know what size the centerbores (mustang vs. max) but maybe some centering rings may help? Where would I get em? Also, I had them use tape weights on the inside (static/dynamic, I don't remember). Even though I watched the machine balance out the wheel at 0.00, do you think I should try using weights on inside and outside to get a better balance?

 

or none that I can really feel. This is w/ rims that have some scrapes and used tires. I was just carefull when I put the wheels on. I could be that the tires are slightly out of round. Balancing gets tricky if not impossible. Did they vibrate when you had the 245s on? Here some pics from our latest meet. http://www.members.home.com/nismonw/meet.htm
