Forged Narrow Superlite 6R Big Brake Front Brake Kit (Hub)

 

FNSL6R billet Forged six-piston calipers with 13”-14” rotors deliver the ultimate combination for braking power and style in this group of kits engineered for traditional non-ABS spindles on American muscle cars and vintage rods. Built exclusively for 17” and larger wheels, SL6 kits enhance tire and suspension upgrades on all types of custom show and high performance dual-purpose street and track machines. A full range of options for caliper finishes and rotor designs are guaranteed to catch the eye of the most discriminating enthusiast while providing optimized brake performance for every individual application.

Specs

Our rotors are machined and fully e-coated, just like the rotor hats. This is a protectant coating the prohibits surface rust from forming on the exposed surfaces. Once the parts are installed and being bedded in, the brake pad friction and caliper pressure will remove the coating at the spot the brake pads touch. This will expose the silver iron material underneath.
