{"product_id":"wilwood-120-16087","title":"Wilwood Right Aero4-ST Caliper for 1.25-Inch-Wide Rotors, Anodized","description":"\u003cp\u003eThe rotor and bracket determine whether this anodized Wilwood Aero4-ST right brake caliper is the correct choice. Its 1.25-inch rotor-width configuration works with the radial mount and 4-piston layout detailed below. Wilwood Engineering, founded in 1977 by Bill Wood, is based in Camarillo, California. The company designs and manufactures disc braking equipment for motorsport, street-performance and specialized use. Calipers, rotors, master cylinders, valves, fittings and brake lines form a range whose individual components must be matched to one another. This Aero4-ST uses four Thermlock insulated pistons with the thick 6620 pad outline. Check the exact unequal bore combination and the 7.09-inch radial mount against the existing installation; the caliper is not selected by color or rotor diameter alone.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 120-16087\u003c\/li\u003e\n\u003cli\u003eComponent: Aero4 Radial Mount; one individual caliper\u003c\/li\u003e\n\u003cli\u003ePlacement: Right\u003c\/li\u003e\n\u003cli\u003eConstruction and finish: Forged aluminum; Type III Anodize\u003c\/li\u003e\n\u003cli\u003ePistons: 4; Thermlock insulated; bore dimensions 1.75\/1.50 inches\u003c\/li\u003e\n\u003cli\u003eHydraulic piston area: 4.17 square inches\u003c\/li\u003e\n\u003cli\u003eDust boots: No\u003c\/li\u003e\n\u003cli\u003eBrake pad shape: 6620; shape number does not specify a friction compound\u003c\/li\u003e\n\u003cli\u003eNominal rotor width: 1.25 inches\u003c\/li\u003e\n\u003cli\u003eRotor width range: 1.10–1.28 inches\u003c\/li\u003e\n\u003cli\u003eRotor diameter range: 12.19–15.00 inches\u003c\/li\u003e\n\u003cli\u003eCaliper weight reference: 7.1 lb\u003c\/li\u003e\n\u003cli\u003eMounting interface: Radial; mounting centers 7.09 inches\u003c\/li\u003e\n\u003cli\u003eMounting-hole diameter: 0.45 inches\u003c\/li\u003e\n\u003cli\u003eMount height: 2.09 inches\u003c\/li\u003e\n\u003cli\u003eHydraulic inlet thread: 1\/8-27 NPT\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eVerify the radial mounting interface and the complete rotor-width range shown above.
