Wilwood AERO4 Rear Kit 14.25in Red 2008-2009 Pontaic G8 w/Lines

The Wilwood 140-12932-R AERO4 Big Brake Rear Kit is engineered to provide high-performance braking for the rear axle. It features the AERO4 4-piston caliper finished in red powder coat and a 14.25-inch GT slotted rotor constructed from Spec-37 iron. This kit is specifically designed to improve stopping power and thermal management over the stock rear brake system.

The kit utilizes BP-20 street performance brake pads for an optimal balance of friction and low noise. It is designed to work with factory master cylinders and incorporates a mechanical parking brake system. The 14.25-inch rotors offer a significant increase in thermal mass compared to the original equipment, effectively resisting fade during aggressive driving scenarios.

Installation involves replacing the stock rear brake assembly with the provided Wilwood components. It requires basic hand tools and is intended to be a bolt-on replacement, though it may require specific wheel clearance due to the large 14.25-inch rotor and AERO4 caliper. Ensure that 18-inch or larger wheels are installed to provide necessary clearance for this system.

This kit is designed for compatibility with the Pontiac G8 model range. It is not intended for all vehicle configurations; please verify clearance with existing wheel sets before assembly. This kit is a significant upgrade for performance-oriented street use, providing increased clamping force and improved cooling over stock components.
