A matching flange pattern alone does not establish rotor alignment or caliper clearance. Use the correct dynamic mounting hardware and rotor connection; an ordinary fixed-mount bolt set does not establish the specified floating assembly.\u003c\/p\u003e\u003ch3\u003eManufacturer Reference\u003c\/h3\u003e\u003cp\u003e\u003ca href=\"https:\/\/www.wilwood.com\/Hats\/HatProd?itemno=170-13170\"\u003eWilwood component specifications and dimensions\u003c\/a\u003e\u003c\/p\u003e\u003cp\u003ePMB Performance can help identify the required brake component with over 20 years of parts experience.
