• Forged Narrow Superlite 4R four-piston calipers

A Genuine Big Brake Kit for the Rear

This kit combines forged Narrow Superlite 4R four-piston calipers with BP-10 compound pads and 12.88-inch rotors, built for custom high performance street and show applications rather than a generic universal fitment. Despite the serious upgrade in braking hardware, this kit retains full use of the OE parking brake, master cylinder output, and ABS where used, so you're not sacrificing any factory functionality to gain real stopping power. This version uses Wilwood's standard rotor and caliper finish, a proven, no-frills setup for anyone who prioritizes function over cosmetics. It's a straightforward improvement that's easy to appreciate once it's installed.

Built to Complement a Complete Brake Upgrade

FNSL4R rear kits provide complementary style and performance when paired with 13-inch and larger front brake upgrades, working alongside wheel, tire, and suspension upgrades as part of a complete build. Optional caliper finishes and rotor designs let you match style and performance across your entire braking setup rather than having mismatched components front to rear. It's a serious rear brake upgrade built specifically to pair with an equally serious front setup. That combination of durability and performance is what makes it worth the upgrade.
