Wilwood EPB Rear Kit FNSL 12 Bolt 2.75 OffSet

Wilwood is well-known for making high-performance braking systems for a wide range of vehicles. This rear EPB (Electronic Parking Brake) kit, part number 140-16165-D, is designed for enthusiasts looking to significantly upgrade their vehicle's stopping power and parking brake functionality.

This kit features a 12.88-inch SRP (Spec 37 Geomet) rotor, which is a strong, heat-treated iron alloy known for its thermal stability and resistance to warping under heavy use. The FNSL caliper is a forged aluminum, four-piston caliper that offers a solid foundation for braking performance. The electronic parking brake mechanism is integrated directly into the caliper, simplifying installation and operation compared to separate cable-actuated systems. The 12-bolt mounting pattern with a 2.75-inch offset ensures compatibility with many common rear axle setups, though it's always best to verify your specific axle requirements.

When installing a big brake kit like this, it's important to consider that you may need to upgrade your master cylinder to properly balance the braking system. Wilwood calipers are typically designed for optimal performance with their own master cylinders. This kit is a substantial upgrade, and you can expect improved pedal feel and significantly more consistent braking performance, especially during repeated hard stops.
