I used .940 T bars on the Challenger. I have a triangulated 4 link set up from Art Morrison. I did quite a lot of research on the rear suspension and from what I gave figured out it should work well. Plus it gives me more space under the rear end. I want to run 315's on the rear and have already widened the rear tubs.
