Made in the USA, theres no competition when it comes to SSBC Performance Brake Systems Competition Series front brake conversion kits. The kit includes Competition 4 piston aluminum calipers with 45mm stainless pistons, performance pads, mounting brackets, Big Bite cross drilled rotors and hardware. The calipers are constructed from billet aluminum and assembled with stainless steel pistons and Teflon coated bleeder screws. This caliper provides 25% more pad contact area than other calipers and 20% greater pad thickness. The dual pad pin design with o rings eliminates pad chatter. Available in both street and race versions (race versions dont have dust seals), the kit uses an off the shelf D43 pad available at any local parts store.
