DFC 67-74 Buick Gs 400 Front Left Drilled & Slotted Geoperformance Rotor

This is the DFC Geoperformance front left drilled and slotted rotor, part number 830-47004L. It's built to fit a variety of classic GM vehicles from the late 60s and early 70s, including models like the Buick GS 400, Chevrolet Camaro, and Oldsmobile 442. These rotors are designed to offer improved stopping power and heat dissipation compared to standard, plain rotors.

The drilled holes help vent hot gases and moisture away from the braking surface, which can reduce brake fade during hard stops. The slots on the rotor also help to sweep away dust and gas, keeping the pad surface cleaner and ensuring more consistent contact. This combination of drilling and slotting makes them a solid option for drivers looking for a noticeable improvement in their braking performance, especially if they encounter frequent hard braking situations or drive in varied conditions.

When replacing rotors, it's always a good idea to inspect your brake pads and consider replacing them at the same time to ensure optimal performance and even wear. Refer to the manufacturer's installation instructions for specific details regarding pad and caliper compatibility.
