What to know before you order for the RX350

Front kits for the Lexus RX350 (2016–2020) use 295–410 mm rotors on this car, with 4-piston, 6-piston and 8-piston calipers from AP Racing, Brembo, Endless and TTSPORT. Brembo 4-piston rear kits with 380 mm rotors are matched too.

With the rotor we recommend for this car, a few front kits work with 16- or 17-inch wheels and a few need 18 inches, but most call for 19 to 21 inches. Rear kits need 19-inch wheels. Spoke shape and offset play a part as well, so give us your wheel details and we will confirm fitment before building.

Almost all RX350 kits mount on brackets made for this car, including those built around genuine Cadillac or Ford calipers made by Brembo. An OEM-style direct-mount front kit that bolts to the factory caliper mounts is also listed. Rotors are high-carbon steel or carbon ceramic; the kits are street kits, with a track-focused front kit available.

Common questions — Lexus RX350 AL20

Can I keep 18-inch wheels with an RX350 front kit?
With some kits, yes. With the rotor we recommend for this car, about a third of the front kits work with 18-inch wheels or smaller, while the rest need 19 to 21 inches. Whether your wheels clear also depends on spoke shape and offset, so send us the wheel details before ordering.
Which rotor sizes are right for the Lexus RX350?
On this car the front kits use rotors from 295 to 410 mm and the rear kits use 380 mm. Smaller rotors suit smaller wheels, while the larger sizes need 19-inch wheels or more. Choose based on your wheels and we will check the match.
Do RX350 rear kits use genuine Cadillac calipers?
Some do. Rear kits for the RX350 come from Brembo with 4-piston calipers and 380 mm rotors, and among them is a kit built around genuine Cadillac calipers made by Brembo, fitted on brackets made for this car.
