Hello, I've read threw quite a bit of this thread, but I just wanted to see if I could confirm this.
Although it might be a bit, I'll be looking at buying some 15x10 (back) wheels and fit as much rubber w/o cutting anything up on my 71 challenger. I have a b body rear end out of a 69 1/2 a12 Coronet dana with 4.10 gears, that I plan on putting in my challenger to help with tire clearance. I purchased the Dr Diff 1" offset shackles. He recommended I run a 28x12x15 (305x54x15) MT Street Radial on a 15x10 wheel with 5.5 inches of backspacing he said it will work w/o spacers if I use his rear disc brake setup. So the question I have is has anyone else done this setup? Not sure what to run in the front yet, right now I am focusing on the rear and making sure things fit w/o any tubing/cutting. I'm also looking at running the caltracs leafspring/traction bar setup as well.
