Genuine BMW Motorsport F82 M4 GT4 Wheels.

Size - 18x 11J
Offset - ET30
Weight - 9.2kg each (20lbs)
 

Fitment - For road cars
While it is an easy fitment on the rear axle, these are not a direct fit to the front axle of a standard M3/ M4 road car without spacers. 
 
The M4 GT4 racecar has revised suspension geometry and alignment settings and a wheel spacer that allows this wheel to fit on the front axle.
 
This wheel will not fit the front of a standard road car without the 32mm spacer.
Spacer kit comes with 2x 32mm spacers for the front axle.
(Only 1 spacer kit is needed per set of wheels ordered)
