If you’re looking to upgrade your braking game, let me tell you about this rear brake system. It’s got a 6-piston caliper that’s mounted to a beefy 14-inch two-piece rotor, which is not just any rotor—this one’s slotted, drilled, and zinc plated. That means it’s built to handle some serious heat and keep your stopping power consistent, even when you’re pushing your ride to the limits.

One of the standout features here is the stainless steel brake hoses. They’re tough and reliable, plus the calipers come with D.O.T.-compliant dust and weather seals. So, whether you’re cruising through rain or kicking up dust on a backroad, these bad boys will keep everything clean and functioning smoothly. The hardware is high-grade stainless, and the rotor comes pre-assembled, which is a nice touch if you want to skip the hassle of piecing everything together.

The 6S and 6R R-Spec calipers are Baer’s pride and joy, made from a single piece of US-sourced 2618 forged aluminum. They’re designed to work seamlessly with the stock park brake assembly, making installation straightforward. No need to reinvent the wheel here—just bolt them on and you’re good to go.

Fitment:

• Perfectly designed for 2004-2006 Pontiac GTO rear spindles and hubs
• Reuses your factory park brake assembly and cables, so you won’t need to hunt for extra parts
