Wilwood 120-17160 D31 Forged Dual Piston Front Disc Brake Caliper

The Wilwood 120-17160 is a Forged D31 Front Dual Piston Brake Caliper engineered as a direct OE replacement for Porsche 911 models equipped with factory "M" 3.00" front caliper mounts. Designed for both street and competition use, this caliper delivers superior strength, reduced unsprung weight, and high-efficiency brake clamping performance over the original equipment unit.

Key Features:

• Forged aluminum body — high-strength, lightweight construction weighing just 4.1 lbs
• Machined stainless steel pistons — for corrosion resistance and long-term durability
• Direct bolt-on fitment — matches the 3.00" mounting centers, height, and offset value of traditional Porsche 911 "M" calipers
• Dual piston design — optimized clamping force for consistent, fade-resistant stopping power
• Compatible with factory components — works with stock replacement rotors (11.10" x 0.80" / 282mm x 20mm) and OEM master cylinders
• Accepts D31 brake pads — compatible with Wilwood and FMSI standard D31 pad compounds
• Type III hard anodize finish — durable, corrosion-resistant coating standard on this part number

The Wilwood D31 caliper series is purpose-built for classic air-cooled Porsche 911 applications, providing a modern braking upgrade without requiring modifications to the factory brake system. Compatible color-finish variants (Black, Red, Yellow) are also available under related part numbers.
