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 12.88 inch GT slotted rotors use Spec-37 iron with a GT-48 curved vane core for strong cooling. Finished in black 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.
