PowerStop JBR939EVC Disc Brake Rotor - Rear

Rear OE-Style Coated Rotor for Lexus LS430

Power Stop JBR939EVC is a rear disc brake rotor built as a direct bolt-on replacement for factory equipment. It is made to original equipment specifications for fit, weight, vane count, and braking performance, with a Genuine GEOMET 360 coating to help resist rust and corrosion.

Compatible with 2001-2006 Lexus LS430 rear brake applications, this rotor supports a clean OE-style replacement for drivers looking to restore braking consistency and corrosion protection. The Power Stop Evolution Coated rotor line focuses on factory-style fitment with a coated surface that does not add friction material to the braking surface.
