Wilwood Narrow Superlite 4R Rear Kit 12.88in Slotted Rotor Anodized 88-96 Chevy Corvette C4

FNSL4R rear race kits provide high capacity braking for dedicated track use on Corvettes and other purpose built vehicles equipped with 1988-1996 C4 Corvette rear suspension. The parking brake is eliminated and the original equipment single piston combination caliper is replaced with a high efficiency, forged aluminum , fixed radial mount narrow Superlite caliper. The forged caliper bodies feature a Type III Mil-Spec, medium gray color hard anodized finish. Hard anodizing provides superior wear resistance in the piston bores and high resistance to abrasion and corrosion throughout. Stainless steel pistons with internal damping springs are used with controlled retraction, high temperature seals for long term durability and consistent performance during extreme duty use. The caliper piston volume is fully compatible and matched to the output of the OE master cylinder on production based Corvettes, and easily configured with balance bar manual brake pedals in non-OE based purpose built race vehicles .

Note for Pistons, Rings, Rotors, Rods and engine internals

Unless otherwise specified, some brands supply brake rotors, pistons, strut mounts, rods and rings separately. In some cases, titles may indicate plural, or 'set' - eg the term “ring set” often refers to the rings for a single piston only.

Features and benefits:
• FNSL4R/ST calipers use a forged aluminum body and feature a Type III Mil-Spec, medium gray color hard anodized finish that provides superior wear resistance in the piston bores, and high resistance to abrasion and corrosion throughout
• Thermlock pistons are used to reduce heat transfer from the pads to increase fade resistance, and extend service life by decreasing temperatures in the caliper body, fluid, and seals
• Internal damper springs and controlled retraction, high-temperature piston seals assure consistent pedal height from start to finish
• Caliper piston volumes are matched for full compatibility with the OE master cylinder output and ABS controls
• Calipers are also fully compatible with manual brake conversions to balance bar pedals using appropriately sized master cylinders.
• Spec 37 alloy GT Series directional vane 13 in. rotors are dynamically mounted using Wilwood Dynamic Lug Mounting system to forged aluminum hats
• Hats are hard anodized for superior wear resistance and extended service life at the load bearing surfaces
• Mounting brackets include all premium grade fasteners and secure the calipers to the uprights in the stock location with no modifications required
• High-temperature, high-friction, race compound pads selected specifically by application
