This braking system showcases a robust 4-piston S4 caliper paired with an 11" two-piece slotted and drilled zinc-plated rotor. The S4 caliper comes equipped with D.O.T compliant dust and weather seals, and it’s compatible with the widely used DR1 or HB100 pad types. With its 1.75" pistons, the S4 Deep Stage caliper delivers extra clamping force compared to the standard S4 caliper. While this added force is great for drag racing, it might not be the best fit for everyday street driving.

The rotors come pre-assembled using high-grade NAS stainless hardware, and we’ve included all the necessary mounting brackets and hardware for your convenience. What makes the SS4+ Deep Stage system stand out is that it’s the first drag race setup designed specifically for heavier, faster cars that may also hit the streets.

The 11" SS4+ Deep Stage system fits most wheels that are 15" or larger. Note: This system is intended for racing use only. If you decide to use it on the street, please take the time to ensure everything is adjusted correctly due to possible changes in brake bias.

This system is compatible with rear ends featuring Dana 60 or Mopar 8-3/4" car housing ends.
