Select Drilled/Slotted B rake Rotor

The StopTech Select Drilled/Slotted Brake Rotor is a high-performance front brake component engineered for drivers who demand superior stopping power and thermal management. Designed as a direct OEM replacement for 1997–2005 GM vehicles, this drilled and slotted rotor serves law enforcement, fleet operators, and enthusiasts running heavy duty or high-performance brake applications. The purposeful design addresses fade and brake dust accumulation—two critical factors in extended duty cycles or demanding driving conditions.

Construction from cast iron with a 278 mm outer diameter and 32.3 mm thickness provides the thermal mass necessary to absorb and dissipate heat during sustained braking. The drilled pattern reduces weight while improving air circulation around the rotor surface, accelerating heat evacuation and reducing thermal shock to the friction material. The slotted design sweeps brake dust and outgassed particles away from the pad contact zone, maintaining consistent friction and extending brake pad life—a measurable advantage in high-mileage or stop-and-go operational environments. Weighing 15.35 lbs with a 5 x 118 mm bolt pattern, the driver-side rotor integrates seamlessly into factory suspension geometry.

Law enforcement fleet managers and tactical operators running extended pursuit or transport duties will recognize the value of reduced brake fade and improved modulation under sustained pressure. Installation is straightforward for technicians familiar with OEM brake service on GM platforms; the rotor simply replaces the factory component using existing hardware. Pair this rotor with high-quality friction material rated for the intended duty cycle—street, sport, or track application—to maximize stopping performance and predictability. Compatible exclusively with 1997–2005 GM vehicles configured with the 5 x 118 mm lug pattern.
