Rotor Flange Billet

The Rotor Flange Billet by JOES RACING PRODUCTS is a precision brake rotor adapter engineered to bridge the gap between Wide 5 hub assemblies and 8 x 7.000 inch rotor bolt patterns. This component is essential for high-performance brake system conversions, particularly in circle track racing, vintage hot rod restorations, and competitive motorsports where weight reduction and accurate brake geometry are non-negotiable. The adapter eliminates the need for custom fabrication by providing a bolt-on solution that maintains proper rotor alignment and load distribution.

Manufactured from aluminum and finished in black anodized coating, the Rotor Flange Billet delivers durability while minimizing unsprung weight—a critical factor in suspension dynamics and brake response. The anodized finish provides corrosion resistance in demanding environments, protecting against moisture and salt exposure common in both racing and long-term storage. Precision billet construction ensures tight tolerances and concentricity, which directly translates to reduced brake noise, extended rotor life, and consistent pedal feel under hard braking cycles. At 0.79 lbs, this adapter contributes minimal mass while maintaining the structural rigidity required for repeated thermal cycling and high-G deceleration events.

Technicians and engine builders restoring classic muscle cars, drag racing platforms, or oval track competitors benefit from this rotor flange's straightforward installation and proven fit. The 8.05 x 8.05 inch profile accommodates standard rotor sizing while maintaining compatibility with Wide 5 wheel hubs common on Mopar platforms and other vintage performance builds. Installation requires only basic mechanical knowledge and standard hand tools, making it accessible for both professional shops and serious enthusiasts. Verify rotor diameter and bolt circle specifications against your brake system before ordering to ensure proper fit and brake balance.
