What is the main benefit of the Z26 Street Warrior brake pads?

The Z26 pads use a carbon-fiber ceramic compound that is designed to dissipate heat better than standard ceramic pads. This helps maintain stopping power during high-speed braking and reduces the likelihood of brake fade.

Why are the rotors drilled and slotted?

The drilled holes and slots in the rotors help to vent heat and gases away from the pad surface. This improves cooling, which leads to more consistent braking performance and can help prevent rotor warping under heavy use.

Does this kit come with everything needed for installation?

Yes, this kit includes the rear brake pads, drilled and slotted rotors, and stainless-steel installation hardware. It's designed as a bolt-on upgrade for your stock brakes.

Product Details

PowerStop is known for making it simple for drivers to upgrade their brakes, and this Z26 Street Warrior kit is a prime example. If you're looking to improve the stopping power on your 2011-2017 Buick Regal, this rear brake kit is designed to handle the demands of performance driving.

This kit includes everything you need for a straightforward bolt-on installation: drilled and slotted rotors, carbon-fiber ceramic brake pads, and stainless-steel hardware. The rotors are zinc-plated to resist rust, and the drilled and slotted design helps with cooling, especially during hard braking. The carbon-fiber ceramic pads are engineered to dissipate heat effectively and produce less dust than typical ceramic pads, meaning your wheels stay cleaner. These pads also feature stainless-steel shims to handle higher temperatures common in performance applications.

This is a complete rear brake upgrade that works together as a system. You get improved stopping power and heat dissipation without needing to modify your stock setup. It’s a solid option for drivers looking for a noticeable improvement in their braking performance.
