The XAT Racing Lexus Brake Upgrade Kit comes with everything you need to bolt on this new brake setup, short of your favorite brake fluid. That includes calipers, rotors, pads, pins, anti-rattle springs, mounting hardware, roll center adjusters, brackets, and stainless braided lines.

Calipers are sourced from a 2007-2020 LS460, LS460L, LS600h, and even the new LS500 4 piston fronts, RWD non-sport package K17 style. We typically source a used set and rebuild them, though we can also get brand new OEM Lexus/Advics ones if you prefer. 

We typically prefer the Posi-Quiet Centric/Stoptech pads, as they have excellent street performance and are not unnecessarily loud/squeaky once properly bedded in. Other options are available as well, if you prefer.

For discs, we use preferred Centric/StopTech 2008-2014 IS-F 360mm (14.2 inch) rotors, not the cheap garbage ones. They come cross drilled from the factory (just like the IS-F rotors are), though we have other bolt on options as well if you're going for a different style or preference. We've not heard of any issues with rotor cracking like some other aftermarket applications have reported.

Please note that calipers are supplied bare natural dark grey. At this time, we do not have a reliable consistent source for powdercoating calipers properly, so we recommend reaching out to places local to you

Although this kit uses DOT approved components, please note it is meant for off road use only. Proper installation is required, and all safety precautions should be heeded. Most parts are readily available, but expect about a 1 week wait for us to have everything together

Additionally, you will most likely need 18" wheels to fit over these. The only 18s we have found to not fit so far are some Enkei RPF1s and IS250/IS350 F Sport front wheels. We cannot make any promises on what else will not fit, however every other 18" wheel we have tried does fit over these brakes, including factory X-Runner wheels, Enkei NT03+, G35 Ray's wheels, etc.
