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 IS-F rear brake caliper upgrade kit 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 IS-F. 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 adapter brackets. This kit DOES NOT include rotors. Please note that this kit requires ISF or RCF rear rotors.
All components in this product kit are proudly engineered and
manufactured here in the United States of America.
