Please note that we offer 2 piece competition rear rotors as an add-on option with this kit! RR Racing Competition 2 Piece Racing Rear Rotors

Our ISX rear brake caliper upgrade kit for the IS utilizes the awesome Wilwood Forged Superlite 4 piston Caliper. This caliper upgrade allows for a huge variety of low-cost rear brake pad options for the ISF. Standard 2 piston rear Brembos are highly limited in costly brake pad options. Additionally, our kit increases rear brake bias which we have found to be effective at the track, especially when coupled with a rear wing/spoiler for down force.

This kit includes the calipers, optional stainless steel brake lines, Wilwood pads, and adopter brackets.

Please note that this kit does not include rear rotors. You need to have ISF rotors to install this kit on the models below. If you don't have ISF rear rotors, then you can either buy the rear kit that includes rotors from our store, or purchase the optional two piece rear rotors with this product.

All components in this product kit are proudly engineered and manufactured here in the United States of America.
