Wilwood Front Red Six-Piston GT Kit for 350Z (2003–2009) & G35 (2003–2007), Slotted 13.06-Inch Rotors

GT-slotted Spec-37 rotors are matched to red six-piston Superlite calipers in this 350Z/G35 package. The documented 13.06-inch front installation includes the mounting hardware and pads but requires separate flexlines. From its base in Camarillo, California, Wilwood Engineering designs and manufactures disc brake systems for motorsport, street-performance and specialized applications. Founded by Bill Wood in 1977, the company also produces the individual calipers, brake rotors, master cylinders, valves, fittings and brake lines used in these installations. Selection should account for how each component works within 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.

Review the complete fitment table below before purchase, retaining the restrictions attached to the chosen vehicle.
