Will TTII's 17"X8" with a 5" BS work with 245/40 rubbers up front and 17"x9.5" with 5.5" BS with 275/40 rubbers in the rear. If not, what is the biggest (safe bet) rim, back spacing and tire combo you can use on a 68. Ive got a 68 camaro with hotchkis 2" drop front springs and Global West upper control arms with First Gens front disc convertion kit. Rear hotchkis 1 1/2" drop leaf springs with drum brakes. Thanks for the help. I want to get it right the first time.
