Cambered Drive Flange 5 Bolt Wide 5

The Quarter Master Cambered Drive Flange 5 Bolt Wide 5 (part number 176320) is a precision brake system component engineered for high-performance automotive applications requiring robust wheel coupling. This drive flange is built to handle the exacting demands of track-duty vehicles, off-road recovery platforms, and specialty motorsport builds that utilize Wilwood brake systems paired with Wide 5 bolt patterns.

Specification-wise, the cambered geometry of this flange optimizes brake cooling flow and tire clearance during aggressive suspension tuning—critical considerations for vehicles running wide-body kits or extreme camber angles. The five-bolt Wide 5 pattern has long been the standard for vintage drag racing, circle track, and offshore motorsports where load transfer and unsprung weight management directly impact lap times and durability. At 1.65 pounds, this component maintains a lightweight profile essential for minimizing rotational mass without sacrificing structural integrity. Quarter Master's manufacturing standards ensure concentricity and hub bore accuracy necessary for balanced wheel packages and safe high-speed operation.

This flange is purpose-built for operators and enthusiasts who demand OEM-grade coupling interfaces between their custom brake platforms and wheel systems. Whether you're restoring a classic competition vehicle, building a dedicated time-attack platform, or upgrading an existing drag racing setup, proper brake-to-hub interface geometry is non-negotiable for safety and performance consistency.

Quarter Master components are recognized across the motorsports industry for precision manufacturing and reliability under extreme operating conditions. This drive flange is sold individually, allowing point builders and technicians to source exactly the component configuration their specific brake and suspension package requires.
