Looking for a great way to tune your suspension? Agency Power has developed rear double adjustable control arms for your 2013 BRZ to give you more control. Machined from 6061 CNC aluminum for reduced weight and anodized red for long lasting great looks, expect performance for a long time. To improve strength and rigidity, Agency Power has increased the thickness where the shock and sway bar link mount. The factory stamped steel area has very thin walls and flexes under serious racing conditions. In addition to the beefy aluminum design, Agency Power uses a double adjustable setup which mounts to the car. The spherical rod end is a 3 piece design with Teflon lining. Agency Power has used these for years on other control arms with zero failure rates. In between the rod end and the aluminum arm there is a steel turnbuckle for on car adjustment at the track. Fine tune your camber to for maximum performance.
