Wilwood 140-18367-D Aero6 Front Big Brake Kit Mustang II Roadster Shop 14.00" Rotor SRP

The Wilwood 140-18367-D is a front big brake kit featuring the Aero6 six-piston caliper platform, engineered specifically for Roadster Shop SPEC or REVO RS chassis built around the RFS-2 forged spindle. This kit delivers serious stopping power with a modern design and race-inspired aesthetic, making it an ideal upgrade for high-performance street and track builds on Mustang II-based front suspensions.

At the heart of the system is a 14.00-inch Spec37 iron rotor featuring 72 curved vanes in a fully vented design for maximum heat dissipation. The two-piece rotor pairs the iron disc with a lightweight aluminum hat to reduce unsprung weight without compromising structural integrity. The Aero6 forged aluminum six-piston caliper delivers exceptional clamping force with increased piston volume, resulting in stronger braking with reduced pedal effort.

Key Features:

• Aero6 forged aluminum six-piston caliper for high clamping force and low weight
• 14.00-inch Spec37 iron rotor with 72 curved vanes for superior cooling and fade resistance
• Lightweight two-piece rotor with aluminum hat reduces unsprung rotating mass
• Designed for Roadster Shop SPEC or REVO RS chassis using the RFS-2 forged spindle
• BP-10 series street performance brake pads included — optimized for quick response, fade resistance, and extended pad life
• Increased piston volume provides stronger clamping with less pedal effort
• Thicker vented rotor construction improves thermal capacity and long-term durability
• Multiple caliper colors and rotor styles available; track-only upgrades available by custom order
• SRP (Street/Race Performance) designation

Wilwood's Aero6 front brake kit is a complete, bolt-on solution for Mustang II suspension platforms used in street rod, restomod, and custom chassis applications. The BP-10 pads are DOT-compliant and ready for street use right out of the box, while the system's robust thermal management makes it equally capable on the track.
