315x60x15's on my 64 Dart GT

oldmoparsrule, those tires look awesome. I've been tossing up the idea of mini tubing my Duster and cramming some fatties under the wells. I really like the way they look on your car.

DO IT! It's pretty simple on our cars. I tied up the frame (don't waste money on catalog connectors) I mini tubbed it and did the MP relocation kit with MP SS springs. I've had a 15x10 wheel 6.5" BS with a 28-12.5-15 MT et street under it with an A-body 8 3/4 no problems. I still have about 3" between the tire and spring and can fit 2 fingers between the tire and quarter pannel. I did not use an aftermarket wheel tub, just welded in like a 2.5"-3" band. You'll be very happy with the results.
