I am planning on running 315/35/17 hoosier A6 on 17x11.5 rims on the front and 335/35/17 A6's on 17x12.5 rims in the rear for autox, will thos sizes make the abs/tc computer freak out?

They should be OK. The rears are larger in diameter than the fronts. It depends on the EBCM to some degree. I ran 25.3 inch diameter Kumho tires front and rear on both of my C5s. Neither had an issue with equal size tires front and rear. Sometimes I forgot to turn things off when I left the paddock and would run several laps before remembering to turn them off. Never noticed Traction Control getting upset. AH won't be bothered as it is initiated as a function of yaw rate, G load and steering input.
