    As we know, Tesla used big beefy M14 wheel studs on our cars. This limits our wheel choices. Or does it? We just got our new 19x10 Advan RGIII wheels for the front of our track setup, and needed to have the lug nut holes opened up to accept the M14 studs. We went to our friendly local machine...
