Ultralight Wilwood / AP Racing Rear Brake Kit (Polo 6N2 Stub Axle Conversion) – VW Golf Mk1, Mk2, Jetta, Scirocco, Caddy

Uncompromising Power and Precision for Classic VWs

Engineered for the most demanding motorsport enthusiasts and tuners, this brake kit redefines rear axle performance in classic VW Group models. It is a complete Rear Big Brake Kit (BBK) solution specifically designed for conversions utilizing the popular and robust stub axles from the VW Polo 6N2.

If you are building a project for hill climbing (like the legendary Scirocco Berg Cup), time attack, club racing, or if you simply require a reliable, no-compromise braking system for your performance street car, this is the kit built for your needs.

Key Features and Performance Benefits:

Early generation VW cars like the Golf, Scirocco, and Polo have lightweight bodies, which means they do not require excessively powerful rear brakes. All too often, incorrectly sized or overly strong rear setups are mistakenly installed, which severely destabilizes the car during braking. Even the factory rear brake system from the Polo 6N2 is frequently too aggressive for the lighter chassis of the Golf or Scirocco.

This brake kit has therefore been designed with careful attention to this fact, and 24rs guarantees that these common stability issues will be eliminated.

This kit is meticulously designed to provide superior pedal feel, optimal braking balance, and significant reduction in unsprung mass.

Unrivaled Lightweight Advantage

The complete setup is over 5 kg (approx. 5279g) lighter than the factory VW Polo 6N2 brake system and nearly 6.5 kg (approx. 6453g) lighter than the complete VW Golf Mk2 kit! Reducing unsprung weight translates directly into improved handling, sharper suspension response, and better acceleration.

Motorsport-Grade Components

• AP Racing Rotors (Two-Piece Design): Utilizing top-tier rotors from the renowned AP Racing brand ensures unmatched resistance to brake fade and consistent stopping power under extreme conditions. The two-piece design (rotor + aluminum hat) maximizes heat dissipation.

• Wilwood Brake Calipers: Lightweight, rigid Wilwood calipers (typically 2-piston for the rear axle application) guarantee precise modulation and powerful braking force, perfectly complementing the lightweight rear end of classic VWs.

• ARP Hat Bolts (Aerospace Reliability): This kit uses specialized fasteners from ARP (Automotive Racing Products), the globally recognized leader in high-performance engine and chassis hardware. The use of ARP bolts to secure the rotor to the aluminum hat ensures unmatched clamping force, superior resistance to stretching, and absolute reliability even under the immense thermal and kinetic stresses encountered during aggressive track use. This detail confirms the kit’s readiness for competitive motorsport.

Precision Engineering and Optimized Balance

The kit includes specially designed aluminum hats and adapters, enabling the secure, precise mounting of the Wilwood calipers and two-piece discs onto the Polo 6N2 stub axles. The design carefully addresses the specific characteristics of the light rear end in classic VWs, delivering balanced braking force that prevents rear wheel lock-up and maintains vehicle stability.
