Wilwood Front Red AERO6 GT Slotted Hub Kit, 14-Inch, for Wilwood ProSpindles

This Wilwood ProSpindle front conversion uses red AERO6 calipers, GT slotted 14-inch rotors and BP-20 pads. Aluminum replacement hubs and separate hats carry the vented Spec-37 friction rings. The package is dimensioned for Wilwood's spindle geometry, so vehicle model alone cannot establish its mounting compatibility. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings, and brake lines for motorsport, street-performance, and specialized applications.

Fitment & Compatibility

Compare the actual spindle with DS629 and confirm that its bearing and bracket interfaces match the kit. A correct existing ProSpindle can be retained after inspection; it is not included with the brake package. Check the +0.68-inch wheel offset change and full wheel-clearance drawing. Select hydraulic hoses for the chassis and verify the completed brake system's pedal travel and balance.
