Need advice on suspension and brake upgrades

My suspension is custom, the front started with a Heidts universal coil spring/a-arm system with rack and pinion steering from Speedway, installed a set of 5/8" shorter control arms, fabricated a set of mounts and tossed the coil springs for QA1 adjustable coil over shocks. The rear is a narrowed Jaguar independent rear suspension. Because of all that my back spacing is custom sized for it so it probably won't work with stock. My color is 2010 Challenger Plum Purple Metallic. I have 17X8 in front and 18X9 1/2 in back.
did the backs fit in without having to do any work in the wheel well?
