rolling means taking out the Fender
liner and the folding the inner lip of the Fender
up. You basically fold it against the inside of the Fender
to create more room.
That's basically your only option, since it's still at stock ride height.
I guess you could also try to get as much either off of the rear end as possible, or get the Hoctchkis camber links and try to adjust the rubbing away. That worked on my friends 240, but it was in addition to rolling the Fenders
