Product details
GT slotted rear discs and red calipers distinguish this 1989–1998 240SX package. The four-piston hydraulic calipers operate independently of the MC4 parking units, so both hydraulic hose routing and the mechanical cable installation must be addressed during assembly. Bill Wood established Wilwood Engineering in 1977. From Camarillo, California, the company designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings and brake lines, for motorsport, street-performance and specialized applications.

Fitment & Compatibility
Fits the 1989–1998 Nissan 240SX rear applications in the table, with the listed four- or five-lug and ABS configurations. Separate MC4 calipers provide the mechanical parking brake. The included rear flexline kit is 220-18269, 12 inches long. Factory parking-brake cables do not connect to the MC4: order cable kit 330-18324 for 1989–1994 or 330-18325 for 1995–1998 separately. Match the hub register, and follow the caliper and cable-adjustment instructions. Nominal minimum wheel diameter: 18 in; 457.2 mm. The linked wheel-clearance diagram must confirm barrel and spoke clearance; wheel diameter alone does not guarantee fit.
