Engineered for maximum weight savings and wheel fitment flexibility, the VTT F3X Ultimate Rear Drag Brake Conversion Kit is a game-changer for competitive drag racing. This version features stealthy black 4-piston calipers and plain-face rotors, offering a functional and low-profile appearance. Because this kit is offered without pads, it allows racers to source their own specific racing compounds to match their front brake setup or track conditions. By moving to a 15" wheel setup, you gain access to the best drag radial and slick options on the market. This conversion isn't just about fitment; it’s about performance, removing nearly 20 pounds of weight directly from the rear driveline to help your BMW launch harder and faster.
