Fits over the m5 and m3's bbk, same rolling diameter as the m5 and m3 rears (so won't fuck up the LSD), fits on the hubs of all three cars (with a hub centric ring on the e91 and e46). Pulled a BMW trunk jack and wrench out of my dad's car last year before he traded it in. Going to throw it in the trunk whenever going on a long trip in whatever car we're going in.
Surprisingly excited
