I just got my C6Z aligned for HPDE's and ended up with the following:
Front
Camber -1.7 -1.7
Caster 7.4 7.5
Toe 0.01 0.01 (this is my favorite by the way

)
Rear
Camber -1.2 -1.0
Toe 0.08 0.05 total toe: .13
While the 2/10ths of a degree variance on the rear camber is nothing - will it make a difference at 140mph? Or in any other respect?
