Description:
Wilwood Forged Superlite 4R Big Brake rear brake race kits are configured for dedicated road racing on all base, Eco-Boost, and standard production GT model 2015-18 Mustangs. They are the engineered match for the AERO6R/ST front race kits with all emphasis on matched front to rear balance, high durability, and high efficiency heat management, without adding unnecessary rotating or unsprung weight to the driveline and rear suspension.

Wilwood's FSL4R/ST calipers feature a forged aluminum body with a Type III Mil-Spec, medium gray color, hard anodized finish providing superior wear resistance in the piston bores and high resistance to abrasion and corrosion throughout. They are equipped with Thermlock pistons to reduce heat transfer from the pads and increase fade resistance, as well as service life by decreasing temperatures in the caliper body, fluid, and seals. GT competition Series 36 vane 14.00 in. rotors are dynamically mounted to the OE hubs with weight saving forged aluminum hats. As is with the calipers, the hats are hard anodized for superior wear resistance and extended service life at the load bearing surfaces.

Additional caliper features:

* Internal damper springs and controlled retraction, high-temperature piston seals assure consistent pedal height from start to finish
* Piston volumes are matched for full compatibility with the OE master cylinder output and ABS controls
* Fully compatible with manual brake conversions to balance bar pedals using appropriately sized master cylinders
