The Wilwood Forged Narrow Superlite 6R front big brake kit upgrades early full-size Chevrolet and Corvette models with forged aluminum six-piston calipers clamping 14.00in by 1.10in rotors. Each caliper uses staggered stainless pistons and a stiff radial-mount body to resist deflection under heavy braking, while the 72 curved-vane GT slotted rotors add cooling and directional venting. Black powder-coated calipers finish a complete hub-style front assembly that includes calipers, rotors, aluminum hats, hubs, and mounting brackets, sized for 18in and larger wheels.
