I am chasing the last of the bugs of my resto on my 72 Cuda.

Todays roach is the Rear wheels. I am running 18"/ 9.5 Torq Thrust II customs on the rear and the offset / back spacing is wrong. When the car squats the tires get into the fender lip. I know someone is running 18's/9.5 on the back please let tell me what offset / back spacing I need.

Thanks

What size tires. Should be 5.5" backspacing but if you have really wide tires you may want to try and get closer to the springs using a 6" backspacing and make up the diff with 1/4 spacer.
