KIT REAR FDLI DISC/DRUM BOP2.75 OFFSET

The KIT REAR FDLI DISC/DRUM BOP2.75 OFFSET from Wilwood is a specialized rear brake conversion system designed for street machines, muscle cars, and custom hot rods that require enhanced stopping power. This kit provides a solution for upgrading rear braking performance while retaining drum brake geometry and existing suspension architecture, making it ideal for retrofitting classic vehicles or for staged brake upgrades.

This rear brake assembly features Wilwood's FDLI (Four-Piston Disc/Light Inboard) design combined with a hybrid disc/drum configuration optimized for BOP (Buick-Oldsmobile-Pontiac) platforms. The engineering ensures balanced braking bias and eliminates traditional drum brake fade during sustained hard braking, providing a consistent pedal feel across repeated cycles. The 2.75-inch axle offset is essential for proper caliper-to-rotor clearance and suspension geometry compatibility.

Technicians and performance enthusiasts working on first- and second-generation BOP muscle cars, such as Pontiac Bonnevilles, Oldsmobile Cutlasses, and Buick GSX models, will find this kit particularly beneficial. The modular design allows for phased installation, enabling users to retrofit the rear kit now and add front upgrades later as budget permits, all while sharing the same master cylinder and proportioning logic.
