I can't believe the BS I hear sometimes. I went to pick up my CF after them taking a week to figure out what is out of balance and they tell me the shaking is just normal for low-profile tires when they are cold.

Ok, I look stupid, but come on. First of all, low profile tires should have less of an impact on the overall wheel balance since the mass is not much further from the center of the wheel. Second of all, the price they pay for these tires and the cars they put them on should be smooth as silk.

Have any of you had vibration on the car at low speeds? Mine appears to be drive shaft or transmission tail shaft related, since the frequency is relatively high for the speed -- it shakes to fast to be tires out of balance I think.

If anyone has had this problem and figured it out it would be helpful. I told the dealer to keep it until they got it figured out.

Also $78 for labor to change the oil. Geeze, practically disassemble the engine in that amount of time.
