The H&R Trak+ 30mm hubcentric wheel adapter lets you convert BMW wheels with a 5x120 bolt pattern and 72.5mm center bore to a 5x100 bolt pattern with a 57.1mm center bore, accounting for the differing stud threads noted in the spec. The 30mm spacer moves wheels outward for a flush stance while maintaining hub-centric alignment and uses a high-strength proprietary alloy made in Germany for dedicated bolt-pattern conversion.
