Wilwood 140-18251-D AERO6 6-Piston Front Big Brake Kit 14" Drilled Rotors - Nissan 240SX / Skyline

The Wilwood 140-18251-D AERO6 Front Big Brake Kit delivers race-proven, high-capacity stopping power for the 1989–1998 Nissan 240SX (S13/S14) and compatible Skyline platforms. Designed around Wilwood's forged AERO6 six-piston calipers, this is a true bolt-on big brake upgrade engineered to work with the factory master cylinder and OEM ABS systems without modification.

Key Features:

• AERO6 Six-Piston Calipers — Forged billet construction with matched staggered piston volumes for even pad wear and consistent pedal feel
• 14.00" Directional Drilled Rotors — Staggered vane, directional vented rotors with drilled holes for maximum heat dissipation and sustained high-heat durability
• OEM-Compatible Design — Fully compatible with the factory master cylinder output and ABS function; no master cylinder upgrade required
• Thermlock Piston Inserts — Reduces heat transfer to caliper fluid and seals for improved fade resistance and extended service life
• High-Torque Caliper Mounting — Radial mount design with dedicated vehicle-specific bracket for a precise, secure fit
• Street and Track Ready — Ideal for dual-purpose street/track use, drifting applications, and performance driving events
• Complete Kit — Includes calipers, rotors, mounting brackets, brake pads, and all necessary hardware for a full front brake conversion

The Wilwood AERO6 is Wilwood's flagship caliper platform, offering the highest pad capacity and clamping force in the Wilwood lineup. Drilled rotors (denoted by the "-D" suffix) provide enhanced bite and cooling performance, making this kit especially suited for spirited street driving and track day use. The kit is engineered to be installed using common hand tools and is designed as a complete, direct-fit replacement for the OEM front brake system.

Note: Verify wheel clearance prior to purchase — 14-inch rotors require adequate wheel diameter and spoke clearance. Minimum 18" wheel diameter is recommended. Stainless braided brake lines and a rear brake upgrade are recommended to maintain optimal brake bias.
