I realize there is about an inch difference in height which will cause a slightly lower speed to register on the speedometer. My question is will the 17" wheels from the M3 work on the M4 without causing issues with the car and will they fit over the brakes? I did not get the carbon brake package. Got 5.3% off invoice for those who are interested ordered as follows:
As was said previously, the 17's will not fit, has to be minimum 18. In addition to that, not all 18 inch wheels will fit.
Also whatever setup you go with, you want the height, diameter and circumference to be about the same or you will run into issues with the traction control. It's not just about the speed being off. It is recommended that the circumference is within 2-3% of the stock sizes.
