The Wilwood Forged Narrow Superlite 6R Big Brake Kit allows for the continued use of the factory parking brake, master cylinder output, and anti-lock braking system (ABS). FNSL6R rear kits are designed to work in conjunction with 14.25" and bigger front brake modifications, as well as wheel, tire, and suspension changes, to provide complementary aesthetics and performance. Optional caliper finishes and rotor designs allow the user to match aesthetics and performance on a variety of applications.
