If you spent time at the track, you have likely broken a stud on your BMW. The fix is no fun and less so track-side between races or it can cut short your day of fun. This is the proper fix.
We start with SKF or FAG hubs (BMW Part# 31226757024), and precision mill the opening and a flat on the back of the hub. Drilling is nowhere near precise enough. Then we press in heat-treated alloy steel studs with a tensile and shear strength that exceeds SAE Grade 8 specs by 25 percent. They feature durable black-oxide plating, and fatigue-resistant rolled threads.
Fits: E36 (all), E46, E85, E86 (non-M). Confirm Part#
