Wilwood 140-17656-DY D31 Rear Disc Brake Kit with SRP Drilled Rotors – Yellow Caliper

The Wilwood 140-17656-DY is a complete D31 rear disc brake kit engineered as a direct-mount replacement for Porsche 911 models equipped with "M" 3.00" OEM rear calipers. Built around Wilwood's forged aluminum D31 direct-mount calipers, this kit delivers a significant upgrade in braking strength, clamping efficiency, and unsprung weight reduction over the factory brake system. Calipers are finished in a striking yellow powder coat for a bold, high-visibility appearance under the wheel.
