Wilwood Front Black FNSL6R System - GT Slotted 14.00-inch Rotors for 2004–2006 Pontiac GTO

Black FNSL6R calipers and 14-inch GT slotted rotors build this front upgrade around the Pontiac GTO original hubs. Unlike many separate-hose kits, this package includes the specified 220-14177 flexlines and fittings. Bill Wood established Wilwood Engineering in 1977. Based in Camarillo, California, the company designs and manufactures disc brake systems, calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications. The requirements of the complete brake system govern the choice of individual components.

Fitment & Compatibility

For the 2004–2006 Pontiac GTO applications shown in the table below, using the original front spindles and hubs. The aluminum hats carry a 1.000-inch offset and clearance for the factory five-lug pattern. DS-537 requires minor hard-line repositioning to align the new fittings. This kit includes the 220-14177 hose package; it should not be ordered as though flexlines were absent. Verify the wheel-clearance drawing and evaluate front-to-rear balance after installation. Nominal minimum wheel diameter: 18 in; 457.2 mm. Compare the actual wheel barrel and spokes with the linked clearance drawing; diameter alone does not establish fit.
