Verify bracket alignment, rotor centering and the actual 1.04-inch width; a vehicle model name cannot establish fit for a fabricated rear conversion. Check hydraulic balance and master-cylinder compatibility for the smaller rear piston area. The M10 × 1.50 banjo inlet requires an appropriate hose end. Arrange parking-brake provision separately where needed, inspect retained rotors and measure wheel clearance before testing.\u003c\/p\u003e\u003cp\u003eWilwood installation documents: \u003ca href=\"https:\/\/www.wilwood.com\/PDF\/DataSheets\/ds844.pdf\"\u003eInstallation instructions\u003c\/a\u003e.\u003c\/p\u003e\u003cp\u003ePMB Performance has over 20 years of brake-system experience.
