Wilwood 140-18251 Aero6 Front Big Brake Kit for Nissan 240SX 1989-1998 / Skyline

The Wilwood 140-18251 Aero6 Front Big Brake Kit is engineered for the Nissan 240SX (1989–1998) and Skyline platform, delivering serious stopping power for street, show, and track applications. The Aero6 six-piston caliper design was purpose-built to provide maximum braking capacity, especially when paired with larger-diameter rotors that standard OEM setups simply cannot accommodate.

This kit is fully compatible with the OEM master cylinder output and factory ABS systems, making it a direct-upgrade solution without requiring significant hydraulic modifications. Whether you're building a dedicated track car, a dual-purpose street/strip machine, or a show vehicle with serious brake presence behind the wheels, this kit delivers both form and function.

Key Features:

• Aero6 six-piston calipers engineered for high-capacity braking performance
• Directional staggered-vane rotors (14.00" to 14.25" diameter) for maximum airflow and sustained high-heat cooling
• OEM master cylinder compatible — works with factory brake hydraulics and ABS
• Ideal for street, track, and show dual-purpose builds
• Provides enhanced braking performance when upgrading to larger wheel and tire packages
• Designed for high-heat durability under extreme and sustained braking conditions

The Wilwood Aero6 is the flagship of Wilwood's performance caliper lineup, offering the greatest braking torque capacity in the street/track segment. The 140-18251 kit includes all necessary hardware for a complete front brake upgrade on the specified Nissan chassis.
