Founded by Bill Wood in 1977, Wilwood Engineering is based in Camarillo, California. The company designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings and brake lines. Its motorsport, street-performance and specialized applications require individual components matched to the complete brake system.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 140-17985\u003c\/li\u003e\n\u003cli\u003eBrake assembly: front conversion kit; Sold as a kit.\u003c\/li\u003e\n\u003cli\u003eCalipers: Forged Narrow Superlite 6R; 6 pistons per caliper; Black Powder Coat\u003c\/li\u003e\n\u003cli\u003eCaliper mounting: Radial\u003c\/li\u003e\n\u003cli\u003eIncluded pad compound: BP-10\u003c\/li\u003e\n\u003cli\u003ePiston material: Stainless\u003c\/li\u003e\n\u003cli\u003eHydraulic caliper inlet: 1\/8-27 NPT\u003c\/li\u003e\n\u003cli\u003eRotor dimensions and construction: 12.88 × 1.10 inches; Spec-37 Iron; GT Slotted\u003c\/li\u003e\n\u003cli\u003eWheel-size reference: 17 in; the complete wheel-clearance drawing determines fit\u003c\/li\u003e\n\u003cli\u003eRequired separate assembly: Wilwood aluminum ProSpindle sealed-hub kit 830-17728; brake kit does not include the spindle or hub\u003c\/li\u003e\n\u003cli\u003eHat mounting pattern: 5 × 4.50 \/ 4.75 inches; verify the mating ProSpindle hub and wheel arrangement\u003c\/li\u003e\n\u003cli\u003eHydraulic flexlines: Not included; supply suitable hoses and fittings separately\u003c\/li\u003e\n\u003cli\u003eMounting hardware: Included; verify the installed fastener engagement\u003c\/li\u003e\n\u003cli\u003eNot included: spindles, wheel hubs, master cylinder or brake booster\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eThis Superlite front package requires the specific Wilwood aluminum 2.00-inch-drop ProSpindle and sealed hub 830-17728. Six-piston radial calipers align with 12.88 × 1.10-inch rotors and the 1.875-inch-offset hat. Compare the separate hub with the 5 × 4.50\/4.75-inch hat drilling and inspect registration before assembly. DS-1615 identifies the brackets and caliper-height procedure for the 12.88-inch kit. Check the wheel drawing and steering geometry, and provide compatible brake hoses separately. The front-steer arm supplied with the separate ProSpindle kit does not establish correct rear-steer geometry; rear-steer arrangements require application-specific steering arms.\u003c\/p\u003e\u003cp\u003e\u003ca href=\"https:\/\/www.wilwood.com\/PDF\/DataSheets\/ds1615.pdf\"\u003eWilwood installation and compatibility information\u003c\/a\u003e · \u003ca href=\"https:\/\/www.wilwood.com\/PDF\/Flyers\/fl617.pdf\"\u003eProSpindle kit configurations\u003c\/a\u003e\u003c\/p\u003e\u003cp\u003ePMB Performance brings over 20 years of parts and fitment experience to component selection.
