Been discussed a couple of times, here's the latest discussion:
Black Powder Coated Wheels
I may go the BMW lug route soon. I ditched the lock lug for that I knew one day that was going to be an issue and it did! Lost the key, left it in the rim after doing a test run in the Roadster and heard it get flug out off into the wild abyss. Tesla was very kind to lend me their master locking key set (12 or more lock combinations) and bust the locks off. They also supplied 4 stock torx bolts to replace the locks as goodwill.
One thing to note is that some people on the Lotus Forum have reported the BMW lugs loosening, but others have not. If you do put the BMW bolts on, as a matter of fact any aftermarket wheel lug, always recheck them after the 1st drive, 5th drive, 12th drive, etc. until you feel comfortable they haven't backed out on you. Thread and pitch is the same and it has a cone shape that mates to the rim so I don't see why they'd back out.
