My plan is to do a front-end 1M conversion and to leave my rolled fenders on the rear end. I'm already able to fit 265-275 tires on the rear, and I might go for standard 1M-size tires (245) on the front. To complete the aesthetic package, I might go for one of the aftermarket rear bumpers (Kerscher?).
You're welcome to use my idea.
