Confirm wheel fit; extended cold use accelerates pad and rotor wear. The conversion combines the caliper, pad and rotor configuration specified for this axle and mounting arrangement. Wilwood Engineering designs and manufactures disc brake systems from its base in Camarillo, California. Bill Wood founded the company in 1977. Its range of calipers, brake rotors, master cylinders, valves, fittings and brake lines serves motorsport, street-performance and specialized applications; each part must suit the requirements of the complete braking system.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eHydraulic inlet thread: 1\/8-27 NPT\u003c\/li\u003e\n\u003cli\u003eBrake-rotor package: 11.75 × 0.81 inches; Spec-37 Iron; GT Slotted\u003c\/li\u003e\n\u003cli\u003eWheel-diameter reference: 15 in; the complete wheel-clearance drawing determines fit\u003c\/li\u003e\n\u003cli\u003eRetained-axle rotor mounting pattern: 4 x 3.93 inches; this does not change the retained hub or axle wheel pattern\u003c\/li\u003e\n\u003cli\u003eFlexline supply: Included; confirm correct routing and hard-line connection\u003c\/li\u003e\n\u003cli\u003eInstallation hardware: Included; verify the installed fastener engagement\u003c\/li\u003e\n\u003cli\u003eItems not supplied: spindles, wheel hubs, master cylinder, brake booster\u003c\/li\u003e\n\u003cli\u003eWilwood part number: 140-17938\u003c\/li\u003e\n\u003cli\u003eConversion type: front conversion kit; Sold as a kit.\u003c\/li\u003e\n\u003cli\u003eIntended use: Road Race kits contain high temperature racing pads.

GS, GT, GX and RF derivatives retain their individual year limits in the table below. Confirm the installed front brake package, retained hub, 4 × 100 mm nominal mounting arrangement and full wheel profile; the 4 × 3.93-inch catalog drilling is the rotor\/hat interface. Follow DS-1622 for caliper centering and supplied hose routing. This road race package uses high-temperature BP-35 pads; prolonged low-temperature operation can cause premature pad and rotor wear.
