Show original supplier description
The Wilwood Forged Narrow Superlite 6R Big Brake Front Brake Kit provides exceptional braking power for performance street and track applications. This kit utilizes the robust FNSL6R six-piston caliper, paired with 14.00-inch diameter SRP (Spec-37 Iron) rotors that are drilled and slotted for optimal cooling and performance. The rotors are finished with a black electro-coat, and the aluminum hats feature a black e-coat. The kit requires a minimum wheel diameter of 18 inches, and users should consult the provided wheel clearance diagram to confirm fitment with specific wheels. A separate line kit (part #220-9111) is required. This kit is compatible with Ford vehicles and requires an 18-inch or larger wheel. For fitment on other makes or models, or for more detailed information, Wilwood Sales/Tech Support can be contacted directly. Users are also advised to check the "Figure 2. Wheel Clearance Diagram" in the installation instructions to ensure adequate clearance.
