The wheels are BMW spec VMRs, i dont know what the exact offset is or size, but my guess is in 8.5 up front 9.5 in the rear. Around a +25-30mm the rears should be around a 20mm. A lot fender work in rear. Front is likely stock.

Tire size is going to make or break the setup. You will need adapters to run the wheels you keep that in mind when choosing them and the offset.
