Billet Specialties says, "When battles are won or lost in less than a second ... you better have the right weapon." If that's how you race, then Billet Specialties Comp 5 Series black wheels are that weapon. Comp 5 front wheels feature one-piece, rotary-forged machined construction with SFI 15.2 certification. Comp 5 rear wheels feature 2-piece construction (spun aluminum rim halves with forged aluminum centers) with SFI 15.1 certification. They're available in a variety of diameters, widths, bolt patterns, and backspacing.
