Product Description

The PERRIN PSP-SUS-136 Front Sway Bar is engineered for Subaru WRX and WRX STI models to deliver enhanced front-end chassis performance and reduced body roll. With its adjustable mounting points, it allows enthusiasts and tuners to fine-tune handling behaviour - whether for spirited street driving or track use. Linking the left and right front suspension towers more rigidly, it improves cornering response and delivers a more confident driving feel.

Installation is straightforward: remove the existing front sway bar (if equipped), mount the PERRIN unit using supplied hardware and torque to specification. The adjustability gives you freedom to dial in your desired stiffness and vehicle behaviour. Ideal for modified WRX/STI builds seeking tighter handling and improved front suspension response without extensive chassis modification.
