{"product_id":"wilwood-140-15814","title":"Wilwood Front Dynapro Radial Sprint Racing Brake Kit, 11.75-Inch Super Alloy Scalloped Rotors and Thermlock Calipers","description":"\u003cp\u003eWilwood's Dynapro Radial front sprint kit is a competition brake assembly built around scalloped 11.75-inch Super Alloy vented rotors. Four-piston calipers use Thermlock pistons and a Type III anodized finish, with BP-40 racing pads specified for the friction interface. The package is for a compatible sprint-car installation, not a vehicle-model street conversion, and requires a separately planned brake-line arrangement. Founded by Bill Wood in 1977 and based in Camarillo, California, Wilwood Engineering designs and manufactures disc brake systems for motorsport, street-performance and specialized applications. Its calipers, brake rotors, master cylinders, valves, fittings and brake lines are selected to suit the complete braking system.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 140-15814.

Bracket-to-upright and hub-mounting hardware, three spacer nuts, spindles, master cylinder and brake booster must be supplied separately as specified in DS-1344.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eCompetition use only; not for street use. This is an outboard front sprint-car brake package, not a model-specific passenger-car kit. Compare the hub\/rotor adapter dimensions and caliper bracket mounting with the installation sheet. DS-1344 requires three customer-supplied spacer nuts to be shortened to 0.93 inch to position the rotor correctly in the caliper. Plan this fabrication step and the customer-supplied mounting hardware before ordering. BP-40 pads require appropriate racing temperature and bedding. Supply suitable braided lines and secure them through the full steering and suspension range.\u003c\/p\u003e\u003cp\u003ePMB Performance has over 20 years of experience working with parts and fitment details.
