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\u003eFor help matching the brake assembly, contact PMB Performance with the ProSpindle identification, hub configuration and actual wheel measurements.
