It really depends on what ride height you desire. The XV 335 will work but I think you'll have to settle for a slightly higher ride height. Myself, I want a low ride height and 335 or 345 tires. I notched the frame and mini tubbed plus stretched the outer half of the wheel wells for safe measure since on a Challenger they angle up pretty hard and wide tires can hit if low. Again I want the tires to be close to the fender not sucked in. I'm no where near complete so only updating on this.
