Product details
The black Superlite front package combines 13.06-inch GT-slotted rotors with six-piston calipers for the listed 350Z and G35 applications. Separate hats retain the original hub interface, while the dust shield must be modified as documented. The manufacturer is Wilwood Engineering, founded by Bill Wood in 1977 and based in Camarillo, California. It designs and manufactures disc brake components and complete systems, from calipers and brake rotors to valves, master cylinders, fittings and brake lines. Motorsport, street-performance and specialized installations each require those components to be matched to the complete brake system.

Fitment & Compatibility
The application list covers Nissan 350Z from 2003–2009 and Infiniti G35 from 2003–2007. The 2007 G35 entry is specifically the two-door RWD model; AWD and later sedan configurations are not established by this kit. Match the listed standard/Brembo brake configuration and the original front spindle.
DS546 requires cutting the front dust shield for rotor clearance and recommends a qualified machine shop. The 13.06-inch rotors fit the retained hubs; hydraulic kit 220-9196 is separate. Inspect the entire wheel profile using the manufacturer’s template.
