Product Description

EBC S4KR1561 is a Stage 4 rear brake kit combining EBC Redstuff ceramic performance pads with USR Sport fine-slotted and vented rear rotors. The kit is cataloged for 2016-2020 Lexus IS300 Base and F Sport models and is designed around the compatible 310mm rear brake configuration. It provides a matched pad-and-rotor upgrade for performance-oriented street and spirited highway driving.

The DP31586C Redstuff pads use aramid-fiber-enhanced ceramic friction material with ceramic granules and incorporate shims, slots, chamfers, and EBC Brake-in coating for controlled bedding. The matching USR7637 rotors are cataloged at 310mm diameter, 18mm thickness, and 67.4mm height, with a 62mm center bore and five mounting holes. Their G3000 cast-iron construction and Geomet coating provide the specified rotor construction and corrosion protection.

The kit includes two USR7637 rear rotors, one DP31586C Redstuff pad set, and caliper lubricant. Verified application data covers the 2016-2017 3.5L V6 IS300 and the 2018-2020 2.0L Turbo I4 and 3.5L V6 IS300 configurations, with Base and F Sport trims listed. Because drivetrain availability varies by year, the vehicle's exact rear brake configuration should be confirmed before installation.
