MGB 11.75" Vented Big Brake Kit – Original 4-Lug Hubs
For use with standard MGB four-lug front hubs.
Looking for considerably more stopping power without changing your original four-lug wheel arrangement? This is the BIG brake upgrade!
Designed for MGBs with increased performance, including V6 and V8 engine conversions, this system combines 11.75" vented rotors with high-performance Wilwood calipers and precision-machined billet aluminum mounting components.
Unlike our five-lug hub conversion kit, this system retains your original MGB four-lug front hubs, making it an excellent choice for those who want serious braking improvements while keeping their existing wheel bolt pattern.
Serious Braking Performance
Whether you're enjoying spirited driving on winding roads, pushing your MGB on the track, or simply looking for more capable brakes to match your engine upgrades, this system provides a substantial step up from the original braking arrangement.
The large-diameter 11.75" vented rotors provide increased braking capacity and improved heat dissipation, helping control brake temperatures during repeated hard stops.
Precision-Machined Components
This isn't a collection of off-the-shelf brackets and adapters. The major mounting components were specifically designed for the MGB application.
The kit includes:
- 11.75" Vented Rotors: Large-diameter rotors designed for improved braking capacity and heat management.
- Wilwood Calipers: Quality performance calipers designed for demanding street and track applications.
- 6061 Billet Aluminum Rotor Hats: Specially machined to fit the original MGB front hubs.
- 6061 Billet Aluminum Caliper Brackets: Precision-machined mounting brackets designed specifically to position the Wilwood calipers correctly.
- Black Anodized Finish: Both the billet rotor hats and caliper brackets are black anodized for corrosion resistance and a clean, professional appearance.
Direct Replacement Installation
The system was designed as a direct replacement for the original MGB front braking components. No suspension modifications are specified for installation.
Simply remove the original brake components and install the upgraded rotor, hat, bracket, and caliper assembly.
Please Note: A minimum of 15" wheels is required to clear the larger rotors and calipers. Steel brake lines are optional. Installation labor and brake fluid are supplied by the installer.
Keep Your Original Four-Lug Wheels
One of the advantages of this system is that you don't have to change your front hub bolt pattern to enjoy substantially upgraded brakes. Retain your original four-lug arrangement while giving your MGB the braking hardware to better match its performance.
