GSF/RCF

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.

Besides the Lexus IS F, the GSF/RCF calipers are a direct bolt-on when using the GSF/RCF front rotors. Because the rotors are 380mm in size, a modification to the front dust shield will be required. Cutting off or bending the dust shield can work too. If you own a 2ND Gen IS or 3RD Gen GS then this entire setup would be bolt on only on the front. There is no current solution for the rear. For 3RD Gen IS, 4TH Gen GS and RC cars, then the rear caliper bolts on using 350phi caliper bracket. For Lexus IS F, the front GSF/RCF front calipers and rotor will bolt on using 350phi caliper bracket ISFGSF1.0. 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. Rear mounting kits has full instructions on installation.

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.
