The SuperPro rear sway bar mounting reinforcement kit for 2013 Scion FR-S spreads load from larger sway bars across extra mounting points to prevent twist, deflection and subframe fatigue. By removing mounting flex the brace improves durability and lets the bar work more effectively, making larger aftermarket bars more reliable without altering the bar's intended tuning or requiring speculative fitment claims.
