Product Details

The DFC Brake Rotor - Drilled and Slotted - Silver line focuses on rotor applications that pair a vented disc design with a machined braking surface layout and corrosion-resistant finish details. For the Pontiac GTO, this rotor uses a slotted X drilled surface and directional braking pattern to match the listed front left position. The silver zinc hat finish adds protection where the rotor is exposed to moisture and road debris, while the plain disc finish keeps the braking surface specification straightforward for service replacement.

This part number 631-52016L is listed for 2005-2006 Pontiac GTO, front left, and uses the specified 5-lug, 120 mm bolt circle with a 71.5 mm center hole. It is a direct replacement-style rotor for the front left brake position on the Pontiac GTO.

Common Brake Issues It Can Address

• Front brake rotor wear at the listed position
• Rotor surface scoring or uneven braking feel
• Corrosion on the rotor hat area
• Brake pulsation related to rotor condition
• Replacement needs for a worn Pontiac GTO front left rotor

Installation Notes

Verify rotor dimensions, bolt pattern, center bore, and position before installation. This rotor is specified for the front left side only and should be matched to the vehicle’s brake setup for 2005-2006 Pontiac GTO applications. Confirm disc thickness and discard thickness during service, and inspect pads, caliper condition, and hub mounting surfaces before completing brake work.

Quality Assurance

Dynamite Friction identifies this rotor with a rust resistant coating and zinc silver hat finish for added surface protection in service. Part number 631-52016L is built to the listed dimensional and fitment specifications for the Pontiac GTO front left brake application.
