I was curious and did some testing with my OEM 355 wheels. The point where the bolts are correctly torqued is very close to the point where you run out of threads. The other issue is the bolt sticks out on the inside as well (where the parking brake is).

So will they work? probably. wheel seemed tight and spun around with out hearing any contact on the inside.
Am I willing to recommend it as the seller? No
