Wilwood 140-14578-R FNSL6R Forged Narrow Superlite 6R 14" Front Big Brake Kit - Red Calipers, Slotted Rotors

The Wilwood 140-14578-R FNSL6R (Forged Narrow Superlite 6R) Front Big Brake Kit delivers a dramatic upgrade in stopping power over factory brake systems. Built around Wilwood's race-proven six-piston Superlite caliper, this 14-inch big brake kit is engineered as a direct, application-specific bolt-on upgrade with full compatibility with your OE master cylinder output and ABS system.

Forged Narrow Superlite 6R Caliper:

• Fully CNC-machined billet body with closed-end bridges and a reinforced bridge-to-body transition for maximum rigidity
• Center bridge body bolts provide additional structural strength and positive pad retention
• Differential bore, six-piston configuration generates high clamping force with balanced pad loading across the full pad face
• Staggered piston sizing compensates for natural variances in temperature, load, and wear rate along the pad length
• Stainless steel pistons minimize heat transfer to brake fluid and resist corrosion
• Signature red powder coat finish for a bold, custom appearance behind the wheel

14-Inch Vented Slotted Rotors:

• Large-diameter vented iron rotors provide substantially greater heat dissipation and cooling capacity versus stock OE rotors
• Slotted rotor faces continuously clean pad surfaces, reduce glaze buildup, and evacuate heat and gases
• Result is smoother, more consistent pedal feel and improved response under repeated hard stops

Complete Kit Includes:

• Two (2) Forged Narrow Superlite 6R red calipers
• Two (2) 14-inch vented slotted iron rotors
• Caliper mounting brackets engineered for direct bolt-on fitment
• Brake pads
• Fittings and flexlines for complete installation

This big brake kit is designed for high-performance street and off-road applications where increased brake capacity is needed to complement wheel, tire, and suspension upgrades. Installation is straightforward using standard hand tools common to routine brake service.
