Detailed Description

This PowerStop coated hat and edge rotor is designed to replace the original rear brake rotor with OE-style dimensions and performance targets. The JBR1151SCR uses a full cast, solid rotor design with a 11.46-inch outside diameter, 4.50-inch bolt circle, and 5-lug pattern. Its rust-resistant coating is applied to the hat, outer edge, and vanes to help preserve appearance and reduce corrosion on exposed surfaces. Fits 2006-2015 Lexus IS250, rear. This part cross-references Toyota/Lexus OE numbers 42431-30280 and 42431-30300 for the same application.

Common Issues Addressed

  • Corrosion on the rotor hat and outer edge
  • Brake pulsation from worn or out-of-spec rotors
