The rear fenders don the familiar Widebody flares to accommodate for the meaty Mickey Thompsons, though the front fenders forgo the unnecessary sheathing in order to save 16 lbs of weight. Under each wheel arch is an optional two-piece carbon fiber wheel made by Lacks Enterprises. These help shave more weight from the Demon 170, bringing the total savings to 157 lbs. Still, expect a curb weight of 4,268 lbs with said wheels equipped; 4,280 without.
