introduction

The cheapest way to give your car larger brakes is by installing brakes from another car. For newer Lexus, the best option is to use brakes from their performance models, the ISF. Lexus ISF comes with large front 6 piston brembo calipers with 356mm x 30mm thick rotors and two piston brembo calipers with 345mm x 28mm thick rotors in the rear.

Another option but more expansive way to achieve larger brakes would be to use brakes from Lexus newer performance models, the GSF and RCF. Both the Lexus GSF and RCF comes with the same braking system. In comparision to the ISF, GSF and RCF comes with larger 6 piston brembo calipers with 380mm x 34mm thick rotors in the front and four piston brembo calipers with 345mm x 28mm thick rotors in the rear.

For older Lexus models, a great option for larger brakes is to use IS350 brake calipers. This setup would give you aluminum 4 piston caliper with 334mm x 30mm thick rotors. A big upgrade compared to many stock 11.6 inch rotors. Also, these older lexus have the ability to use ISF or GSF/RCF brake caliper too.

Our latest discovery comes from the Advics brake caliper on the newest 2023 Lexus RX350 F sport. These large 6 piston calipers with 400mm x 36mm thick rotor are able to be bolted onto 2010 and up Lexus RX (all models), 2015 and up Lexus NX (all models) and many more. These calipers are a direct bolt-on on the front of the car. There are no special adapters needed.
