I have a 1969 Camaro SS with a small block,4-speed and 12 bolt. It sits at stock height and I want to put the biggest tire I can in the back. I'm going with American racing Hopster with a 16X7 up front and either a 17x8 or 17x9.5 in the back. I need to know if the 17x9.5 and what size rubber I could put on either of the rear sizes. Thanks for the Help
