Progress Tech rear sway bar for 2008–2016 Subaru WRX and STi (22mm, adjustable) reduces body roll and improves rear-end traction; note this application requires PN 65.2314. The adjustable design allows step changes in rear roll stiffness to tune handling balance for different driving needs. Cold-formed in-house with CNC bending, laser-cut ends and MIG-welds, the solid 22mm alloy bar uses firmer polyurethane bushings for a precise, durable fit.
