Product details
Red FNSL6R calipers and GT slotted rotors define this 13.06-inch Camaro/Firebird front system. The rotor hats keep the compatible original hubs in service while the bracket mounting depends on the later twin-piston-caliper spindle. Wilwood Engineering designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings and brake lines. Bill Wood founded the company in 1977; its Camarillo, California operation serves motorsport, street-performance and specialized applications. The requirements of the complete brake system govern the choice of individual components.

Fitment & Compatibility
Fits the 1998–2002 Camaro/Firebird front spindles originally equipped with twin-piston calipers. DS-566 identifies castings 18023021 and 18023022. Original 1993–1997 single-piston spindles do not fit; the earlier Camaro rows in the table below require conversion to the later F-body spindle. Retain the compatible hubs, confirm wheel clearance and select separate 220-6746 front flexlines. Check all year, original rear-brake and conversion qualifications in the table before ordering. Nominal minimum wheel diameter: 17 in; 431.8 mm. Compare the actual wheel barrel and spokes with the linked clearance drawing; diameter alone does not establish fit.
