I'm debating about doing some HRE 20's with the same offsets as the M6 wheels. Anyone done similarly?F: 20x9 ET:12 - 255/35F: 20x10 ET: 17 - 285/30From it shouldn't change things much, assuming that the M6 wheels have no fitment issues on a normal 645 (can't think why they would unless the rotor is thicker). Should give about a 1 MPH change in the speedometer at 80, and the tires are within 0.2' in diameter of each other (Michelin PS2) so hoping no DSC issues.I'm debating about going with a little more offset and using a spacer incase additional brake clearance is ever needed.

E63 M6 Wheel Offset Wheels
The standard E60 wheels are size 8.5x19 fronts and 9.5x19 rears. Can anyone assist me in discovering what the wheel offsets are? The offset of a wheel is the distance from its hub mounting surface to the centerline of the wheel. 6er E63+ M6 8,5x19 front ET 12 13,23. Also Style 167 in E63 offset is almost impossible to find, the few ads i have seen for M6 wheels were not m6 but rather m5.2015, 03:31 PM. You can sort the offset with spacers if needed and even go a little thicker for better fitment. If the M6 wheels are cheap it might be worth while.
