FDL Front Drag Brake Kits with Hats are drag racing’s most popular front brake kits. FDL kits are available for the popular Import car spindles or front struts used on four-wheel disc cars weighing up to 2,800 pounds, or rear drum brake equipped cars weighing up to 2,400 pounds. Forged billet FDL four piston calipers mount directly to the spindle with a bolt-on bracket. Forged Hats with direct mount steel rotors combine to provide an average weight savings of over 30 pounds compared to stock drum or disc brakes. Kits include attachment hardware, brake pads, and instructions.
