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

The Wilwood 140-12932-DR is an AERO4 Big Brake Rear Kit designed specifically for the Pontiac G8 platform. This kit features high-performance 4-piston AERO4 calipers in a red powder-coat finish, paired with 14.25-inch SRP drilled and slotted Spec-37 iron rotors. It is engineered to maintain full functionality of the factory parking brake assembly.

The system includes radial-mount calipers for precise alignment and stiffness, significantly improving braking consistency and thermal management over the stock rear brake system. The included BP-10 compound brake pads provide an optimal balance of cold bite and high-temperature fading resistance for performance driving applications.

Installation requires professional-level knowledge of hydraulic brake systems. The kit utilizes radial mounting, which may require specific bracket alignment. Always ensure that the 18-inch or larger wheels intended for use have adequate clearance for the large caliper footprint as specified by Wilwood's clearance templates. Compatible with the factory master cylinder and ABS system.

This kit is designed specifically for the 2008-2009 Pontiac G8 models, including Base, GT, and GXP trims. It is not a universal fitment component and requires the specific axle flange configuration associated with the G8 platform. Ensure that the vehicle's brake lines and hubs are free from debris and in good condition prior to the performance upgrade.
