ISR Performance Rear Trailing Arm Set 2013-2021 BRZ / 2013-2016 FRS / 2017-2021 GT86

The ISR Performance Rear Trailing Arms are designed to bring improved stability and response to your BRZ’s rear suspension. These arms play a critical role in maintaining proper suspension geometry under acceleration, braking, and cornering—especially when the vehicle is lowered or pushed hard on track.

Crafted from high-quality steel and finished with adjustable rod ends, these trailing arms allow for more precise wheel control and tighter handling characteristics without sacrificing ride quality.

Features:

• On-car adjustability for fine-tuning suspension geometry
• High-strength steel construction for long-lasting performance
• High-quality spherical rod ends for responsive handling
• Direct bolt-on fitment to factory mounting points
