BMW also uses lug bolts, I work for a team that ran a 325is in IMSA
endurance last year, we switched, and we got busted... well Davis Racing got
busted, we were told we were next if we didn't straighten up and fly right.

Davis' argument was that studs were safer, but then again, the BMW has very
high safety ratings, and so arguably the German engineers must know what
they are doing.

Incidently, I've noticed that Saab uses bolts, but the hub has a small stud
that you can hang the wheel on and get the bolts started!
