Is the C7 going to get centerlocks?



I know Porsche is going centerlock. Is GM following suit?

Forgot to mention, all 4 corners get 6 puck brakes. Yes, the rears too.

Hope not. There are only 2 advantages that I am aware of in center lock wheels; A) faster wheel changes during a racing event (w/ pit crew) and B) they look cool. But given the choice, I would pick the 5 lug design due to its superior strength, practicality, and overall cost, IMO.

Centerlocks are not good for the common man for the street from a safety perspective. If you change a flat, and torque it down and drive off, and it is not really torqued properly due to dirt or whatever, and the nut starts backing off, you will loose the wheel. With five lug nuts, you have some back-up if one is not torqued properly and backs off.

Smart practice would be to use a safety wire, I don't think manufactures will go down that path due to liability concerns, with untrained owners. The tort enviroment of the 60's (last time I think we saw centerlocks on the street) is dead.

How would it back off? Are centerlocks typically threaded so that if the car is moving forward the thing be moving in the direction which would would tighten itself?
