305 DR's are being run on the stock 9.5" SRT/Hellcat wheels no problem. Width shouldn't be an issue with the right offset (backspacing). Our stock offset with a 9.5 wheel is 18 mm if I read correctly. Wheel diameter shouldn't make a difference on wheel well clearance if an 18 will clear our back brakes.
I missed your visitor message somehow.
