Product details
Red FNSL4R service calipers and red MC4 parking calipers accompany the SRP rotor package for the Nissan 240SX. Its 13.50 x 0.81-inch vented discs use aluminum hats with four- and five-lug patterns, while the braided rear line kit is included. Wilwood Engineering designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings and brake lines. Bill Wood founded the company in 1977; it is based in Camarillo, California, and serves 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.
