The separate spindle\/hub kit supports the documented 5 × 4.50\/4.75-inch rotor-hat interface. DS-1615 identifies the longer caliper studs and additional bracket spacers used by this 14.00 × 1.10-inch package. Verify those components, rotor centering and the complete wheel profile. Hydraulic hoses and any application-specific steering-arm work remain separate. 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\u003eBefore purchase, send PMB Performance the ProSpindle identification, hub configuration and actual wheel measurements.
