I didn't have much luck with the Rays (dur)aluminum lugs--the first keyed one that I tried to torque down bent and lodged itself in the special socket. These are the more expensive Formula lugs...they use a seven-sided hex key on every lug, so in theory they are more secure and hopefully they can at least be torqued without breaking.
I have some more Rexpeed carbon bits on the way (hood and wheel vents).
