Brake kit choices for the IS300
If you drive a 2017 Lexus IS300 (XE30), front kits come from AP Racing, Brembo, Endless and TTSPORT with 4- or 6-piston calipers, and we recommend 330–380 mm front rotors. At the rear, TTSPORT offers a 4-piston kit with a 345 mm rotor.
Using our recommended rotor for this car, some front kits clear 17-inch wheels, most need 18 inches or less, and the largest need 19. The rear kit needs 18 inches. The rotor you choose, spoke shape and offset still play a part, so list your wheel size and offset when you ask us.
Every kit mounts on brackets made for the IS300, and a front option uses genuine BMW calipers made by Brembo. Rotors come in high-carbon steel or carbon ceramic. Most kits are street kits; some front kits are aimed at track use. Kits without an online price have a quote button, and we reply by email within one business day.
