TannedAndTatted

Hey guys so i recently dumped my car on Racelands. Maxed out on all 4 corners. but do i minimize the rubbing? I'm running stock 18s with normal tires. i don't know much about fitment and tire stretching and offsets but i took my wheel wells out and its rubbing a lot less. next step is to roll my fenders. If i can't get my hands on a roller whats the next best way to do it? and does anyone have any pics and numbers and what their running on their cars?
Thanks
