Hey all, I have a 19 hellcat and thinking about getting some stickies. Car is currently lowered on Eighbachs with 20x11 ferrada fr4s wrapped with 315 555r2's. I have read some posts but nothing clear to me on a few questions. I plan on changing the gears to 3.09's in the near future (when time permits). I have the diff but time is hard to come by with 2 littles. Would it be better to run a 305/45/17 or 315/50/17? I really don't want to take a slege hammer to the typical spots where it would rub. But if gearing is an issue I'll have to rethink my game plan. Any help and suggestions is much appreciated.

315 50 17 is ideal on a 17x10.
I get perfect even wear, and alas, my car is lowered on eibach prokit springs. I run a 2 step and it digs from the hole...... Fits tight on a challenger, but looks absolutely killer, and hooks so damn good. A 11 inch wide wheel is a waste of rotating mass in my opinion.....

I do believe chargers have more room
