The PowerStop Evolution Drilled & Slotted Rotor pair is a bolt-on cooling upgrade for 1992-1995 Mazda 929 rear brakes. Precision cross-drilled holes and rounded slots clear gases, dust and moisture to preserve the friction contact patch and improve cooling. Zinc dichromate plating resists rust while chamfered drill holes and rounded slots reduce stress cracking. These rotors are mill-balanced and sold as a pair for easy installation.
