Wilwood 140-17652-R D31 Front Disc Brake Kit for Porsche 911 Red Caliper

The Wilwood D31 Front Brake Kit (140-17652-R) delivers a high-performance, direct-fit upgrade for Porsche 911 models originally equipped with OEM "M" 3.00" front calipers. Engineered for strength and weight savings, this kit centers around Wilwood's forged aluminum D31 direct mount calipers — a direct replacement that matches the exact 3.00" mounting centers, height, and offset value of the factory 911 "M" caliper design.

Key Features:

• Forged Aluminum D31 Caliper Body — Lightweight at just 4.1 lbs, with a high-strength forged aluminum construction
• Machined Stainless-Steel Pistons — Precision-machined for consistent, high-efficiency brake clamping force
• Standard D31 Brake Pads — Included in BP-10 compound for reliable street and performance use
• OEM-Spec Rotors — 11.10" diameter x 0.79" thick; available in plain face or SRP directional drilled and slotted configuration with black e-coat finish
• Red Powder Coat Finish — This kit (suffix "-R") includes calipers finished in red powder coat; black powder coat also available; yellow powder coat, Type III hard anodize, and special powder coat colors available by special order at additional charge
• DOT-Compliant Stainless Braided Brake Hoses — Included for superior fluid performance and durability
• Direct OEM Mounting Compatibility — Same mounting centers, height, and offset as traditional Porsche 911 "M" calipers for straightforward installation

The Wilwood D31 series is a proven solution for enthusiasts seeking to upgrade stopping power while reducing unsprung weight. The combination of a forged aluminum caliper body, stainless pistons, performance brake pads, and quality rotors makes this a complete, bolt-on front brake system.
