Information
Some Lexus model year have the ability to bolt-on IS350/GS350 4 POT Advics or ISF/GSF/RCF 6 POT Brembo front calipers onto the car. These calipers with the right rotors will be a direct bolt-on using a custom bracket. There are two different version of the Lexus Brembo Calipers. 08-14 Lexus ISF or the 15-17 GSF/RCF.
IS350 4 POT front caliper will bolt-on the front knuckle of the listed models with custom bracket. The ISF front brembo calipers are a direct bolt-on with custom bracket if you're using 2013 and up GS350 F Sport front brake rotors. GSF/RCF front brembo calipers are a direct bolt-on with custom bracket when using GSF/RCF front rotors.
There are no special brake lines needed as your car's factory brake lines bolt up. You can purchase Lexus ISF Stoptech SS brake lines and it will bolt up.
If you're powdercoating your calipers, please make sure that you clean and remove any layer of paint around the brake line valve. This will ensure that the crush washer to the brake lines sit flush with the caliper and does not cause any leaks.
Front mounting kits has full instructions on installation. Please download and print out the IS350 BBK template and make sure your current wheels could clear the caliper upgrade.
