Price no problem/factor, and being able to dial in enough negative camber (IF you are using them on a road course, or for serious, 'for the win' autocrossing) the A052s which are also 7.9" tread width.
Other wise, the AR-1s, albeit they will most likely wear even quicker yet on the street (if that's your main use, i.e.; canyon runs) than the A052s, which already have a rep for burning down way too quickly.
The 660s would probably be the best 'compromise' given their price, half decent wear rate, and the fact that you (even in Cali's heat) most likely would NOT shred/tear that center tread strip in the canyons, like the autocrossers do.
