IS F
Information
Some Lexus model year GS, IS, and RC have the ability to bolt-on 6 POT front Brembo calipers onto the car. These calipers with the right rotors will be a direct bolt-on without any use of shims, bracket or spacers. Depending on the model of the car, the rear Brembo caliper can be a direct bolt-on. There are two different version of the Lexus Brembo Calipers. 08-14 Lexus ISF or the 15-17 GSF/RCF.
The ISF calipers are a direct bolt-on if you're using 2013 and up GS350 F Sport front brake rotors. 2015 and up RC350 F Sport also run the same front rotors. Therefore, if you own either of these cars then you would only need the full ISF caliper set, rear ISF rotors and bracket mounting kit. If you own a 2ND Gen IS or 3RD Gen GS then this entire setup would be bolt on. No rear mounting kit required. For 3RD Gen IS, 4TH Gen GS and RC cars, then the rear caliper bolts on using 350phi ISF1.0 caliper bracket. F Sport model cars will not need to cut the front dust shield as it's large enough. Any base model cars will require a change of dust shield for the front or removal/cut of the dust shield. The rear will require a cut of the dust shield on most model cars.
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.
