If you're upgrading your 2001-2006 BMW M3 E46 for serious track use or a high-performance street build, a rear big brake kit like this Wilwood Narrow Superlite 4R setup is a key component. This kit is designed to work with your existing parking brake system, master cylinder, and ABS, ensuring that crucial factory functions remain intact while significantly boosting your stopping power. It's the perfect complement to larger front brake upgrades, wheel and tire changes, and suspension modifications, bringing the whole performance package together.

This kit features Wilwood's forged Narrow Superlite 4R four-piston calipers, known for their solid construction and reliable performance.

Wilwood offers optional caliper finishes and rotor designs, allowing you to further customize the look and performance to match your specific build. This kit includes everything needed to upgrade your rear braking system, providing a substantial improvement over the stock setup.
