Wilwood FNSL4R Red Drilled & Slotted Rear Big Brake Kit - Camaro / Firebird 1998-2002

Wilwood's Forged Narrow Superlite 4R rear big brake kit puts a four piston radial mount caliper with 1.12 inch bores and 1.98 square inches of piston area behind each rear wheel, clamping a 12.88 by 1.10 inch Spec-37 iron rotor with GT 48 curved vanes. This version pairs Wilwood's SRP drilled and slotted rotors, dynamically balanced and black E-coated, with red powder coated calipers, BP-10 pads offering 8.2 square inches of pad area and black E-coated aluminum hats that carry the parking brake provision. The kit keeps the factory parking brake, the OE master cylinder output and ABS where fitted, so it upgrades the rear axle without forcing a change to the rest of the system. A 17 inch minimum wheel diameter is required for clearance.
