Description

The ISR Performance Rear Lower Control Arms (IS-RLC-FRS) are purpose-built for the 2013-2020 Subaru BRZ rear suspension, and share ISR's application designation with the Scion FR-S 13+ on the same 86 chassis platform.

  • Part of ISR Performance's dedicated FR-S/BRZ suspension catalog, which also includes rear trailing arms, rear toe control rods, rear sway bar end links, and a rear diff mount support brace — useful if you're planning a full rear suspension refresh
  • Backed by ISR Performance, a manufacturer focused on developing suspension, exhaust, and drivetrain components for the sport-compact and JDM performance market
  • A practical option for BRZ/FR-S owners replacing worn, aging, or damaged factory rear lower control arms
