I was wondering if putting on a Cobra rear bumper would give me more clearance than my GT bumper for my slicks. 28" tall, rolled lip, quads removed and as it sits now 1" clearance in front of slick and 1" on rear of slick with some modifying to the rear bumper. No problems with width just over all circumferance and that scares me that with tire expansion on the big end it will rub.
