Our front big brake kit is easily on par with the venerable Brembo caliper/rotor found on the Lexus ISF. This kit utilizes Wilwoods massive Aero6, 6 piston front calipers. Unlike the cast aluminum Brembo calipers on the IS-F, the Wilwood Aero6 calipers are forged, and feature internal seals for higher temperature capability. RR Racing brake kit utilizes high quality 14" slotted and e-coated brake rotors, significantly improving the thermal capacity compared to stock rotors. We offer optional Stoptech stainless steel brake lines (not required for daily driving).

Additional brake rotor features:

  • Black E-coating for long lasting corrosion protection
  • Double Disc Ground for quieter and smoother stops
  • Machined finish for a cleaner looking part
  • Center Split core castings for proper heat transfer
  • Slotted using RCF stock rotor slotting pattern
  • Offered in optional powder coated paint colors (see some color samples in the photo catalog for this product) with RR Racing logo (please specify in order notes if you prefer no logo)

All of our brake kits include BP10 pads with the option to upgrade

Please note that we now ship the rear rotors slotted (same pattern as front) not drilled as shown in the photos

All components in this product kit, with the exception of the brake rotor castings, are proudly engineered and manufactured here in the United States of America.

Please also note that we now offer caliper color options (please refer to options for this product) using powder coated paints. All calipers for this product come with RR Racing logo on them. We do not disassemble the caliper for powder coating. Our powder coating quality is good, but it is NOT equivalent to original manufacturer's quality. Some indentations on the rear of the caliper (areas not visible from the side of the car) may not be perfectly covered.

Street friendly
Installed on my daily driver GS and worth the cost. Fits behind stock F sport wheels no issues. Big difference in the feels and bit of the brakes.

Solid system. Installed it on my 2020 IS350 F-Sport and what a huge difference!!! Would highly recommend for anyone looking to upgrade for increased stopping performance. The install was straight forward and took about 3 hours which included flushing and adding high temp fluid.
