Wilwood 140-16946-DY Powerlite PL4R Front Disc Brake Kit - 4-Piston Yellow Calipers, Drilled & Slotted Rotors

The Wilwood 140-16946-DY Powerlite Front Brake Kit delivers a complete, bolt-on front brake upgrade centered around Wilwood's motorsports-proven Powerlite PL4R radial-mount four-piston calipers. Finished in a gloss Le Mans Yellow powder coat over a durable Type-III hard anodized base, the calipers combine eye-catching style with long-term corrosion resistance. This kit uses the factory disc spindle and OE hubs for a clean, direct-fit installation without custom fabrication.

Kit Features:

• Powerlite PL4R calipers — rigid, forged aluminum radial-mount design with four pistons for balanced, high-torque clamping force
• One-piece stainless steel pistons slow heat transfer and resist corrosion for consistent pedal feel
• Quick-clip top pad retainer allows fast pad changes and fits inside smaller-diameter wheels (minimum 15" wheel diameter)
• 11.10" x 0.80" (282mm x 20mm) vented rotors — cross-drilled and slotted from proprietary iron alloy for superior heat dissipation and reduced brake fade
• BP-10 performance brake pads included for strong street and performance driving friction
• Stainless steel Flexlines provide firm, consistent pedal response and resist expansion under pressure
• Caliper mounting brackets and hardware for bolt-on installation to struts with 3.0" (76.2mm) caliper mounting bolt spacing
• Compatible with factory master cylinder — no brake booster or master cylinder upgrade required
• Calipers engineered using FEA (Finite Element Analysis) for optimized strength-to-weight ratio

Kit Includes:

• Powerlite PL4R 4-piston calipers (Yellow powder coat finish)
• Vented, cross-drilled and slotted one-piece iron rotors
• BP-10 performance brake pads
