The Wilwood Forged Narrow Superlite 6R front big brake kit upgrades 1970s GM muscle cars with six-piston forged billet calipers and 12.88 inch rotors. Each caliper carries a stainless piston set with 1.62 inch and 1.12 inch bores for firm, even pad pressure and strong, repeatable stops. The SRP drilled and slotted rotors measure 12.88 inches and shed heat and pad gases while adding cold bite. Finished in red powder coat, the kit bolts to factory non-ABS disc spindles and includes left and right calipers, rotors, an aluminum hat, and a forged hub. A stainless flexline kit (part 220-10509) is required and sold separately, and 17 inch or larger wheels are needed for caliper clearance.
