Progress Tech rear sway bar for 2013–2016 Scion FR-S and 2013+ Subaru BRZ (17.5mm, adjustable) improves chassis balance by reducing body roll and keeping tires flatter for better grip. Its adjustable end lets you modify rear roll stiffness to tune understeer or oversteer tendencies. Cold-formed with CNC bending, laser-cut ends and MIG welds, the solid 17.5mm bar uses firmer polyurethane bushings and is developed and manufactured in-house in the USA.
