GT4 Wheels are on the car! They look fantastic and fitment appears to be a success.
Unique Wheel Property -
This wheel has a back pad that is 15mm thicker than anything that I have seen. As a result, the stud required is at least 15mm longer than typical. There is no stud currently on the market that will accommodate this wheel with a 12mm spacer. BMW's own GT4 studs are designed to accommodate a 32mm spacer - yes you read that correctly - BMW is using a 32mm front spacer on the M4GT4! I am not sure why the wheel was built with that spec but my assumption is that it's due to strength requirements. As a result, we are working with MSI (leading stud manufacturer) to create a custom stud length for this wheel.
