Wheels rubbing after fitting new coilovers.

[pudding]

*correction to the error* - the additional wheel width of 12.7 mm is split in half sending 6.35 mm of the wheel inward and the same outward from the center of the wheel.
Total additional 'wheel' going outward is: 6 mm (change in offset) + 12.7 mm(0.5) = 12.35 mm.

Correct
