Wilwood Front AERO6 Conversion, Red Calipers & Drilled Rotors with Hubs for No Limit ZG Spindles

Red AERO6 calipers provide the hydraulic service braking in this Wilwood front conversion for No Limit Engineering ZG Spindles. They work with 14.00 × 1.25-inch srp drilled & slotted rotors; the vehicle designation must be considered together with the mounting details below. Wilwood Engineering, founded by Bill Wood in 1977, is based in Camarillo, California. Its work covers the design and manufacture of disc-brake systems and components for specialized vehicles, motorsport and street-performance use. The product range includes calipers, brake rotors, master cylinders, valves, fittings and brake lines; compatibility depends on the complete system.

Fitment & Compatibility

For No Limit Engineering ZG spindles only, DS1542 requires removal of the two interfering spindle ears plus drilling and tapping two holes. Both spindles need the specified qualified machining before brake assembly. Check wheel stud location, bearing adjustment and the full 18-inch clearance diagram. The supplied hubs determine the available wheel patterns; the spindle itself is not included.

With more than 20 years of parts experience, PMB Performance can help compare your VIN and installed hardware with the required configuration. Include any suspension, wheel or axle changes.

Review Installation instructions for the complete installation and clearance requirements.
