Wilwood 140-18365-D Dynapro 6 Front Big Brake Kit for Mustang II Roadster Shop RFS-2 Spindle with 12.19" SRP Rotor

The Wilwood 140-18365-D is a Dynapro 6 caliper-driven front big brake kit purpose-built for Roadster Shop SPEC or REVO RS chassis equipped with the RFS-2 forged spindle. This kit delivers serious big-brake performance with modern engineering and a clean, race-inspired appearance.

At the heart of the kit is Wilwood's forged six-piston Dynapro caliper, which provides increased piston volume for stronger clamping force with less pedal effort. Paired with a 12.19" 30-vane vented iron SRP rotor and a lightweight two-piece aluminum hat, this setup improves thermal management and long-term durability under repeated hard stops.

Key Features:

• Forged six-piston Dynapro caliper for high clamping force and reduced pedal effort
• 12.19" diameter 30-vane vented iron rotor for superior heat dissipation
• SRP (Street/Race Performance) rotor finish for enhanced bite and longevity
• Lightweight two-piece aluminum hat reduces unsprung weight
• BP-10 series street performance brake pads included — quick response, fade resistance, and extended pad life
• Engineered specifically for Roadster Shop SPEC and REVO RS chassis with RFS-2 forged spindle
• Available in multiple caliper colors and rotor styles
• Optional track-only upgrades available by custom order

The Wilwood 140-18365-D front brake kit is the ideal upgrade for Mustang II-based custom chassis builds demanding maximum stopping power, reduced fade, and professional-grade style. Multiple caliper finish options allow this kit to complement any custom build aesthetic.
