Hardrace Pillow Ball Rear Toe Arm 2014-2021 WRX/STI

Hardrace Pillow Ball Rear Toe Arm 2014-2021 WRX/STI | High-Strength Steel | Rear Suspension Adjustment

Overview

The Hardrace Pillow Ball Rear Toe Arm is a precision-engineered suspension component designed specifically for Subaru WRX and WRX STI models from 2011 to 2021. This upgrade replaces the factory rear toe arms to allow for fine-tuned adjustments of the rear toe angle, improving straight-line stability and overall road control. Ideal for enthusiasts seeking enhanced handling characteristics and sharper steering response, this toe arm is a key upgrade for both spirited street driving and track use.

Constructed from high-strength steel alloys, the Hardrace toe arm balances durability with lightweight design. The arm undergoes an Electrophoretic Deposition (ED) coating process followed by a durable paint finish, ensuring long-lasting corrosion resistance and strength under demanding conditions. The inclusion of a pillow ball joint reduces deflection and unwanted compliance compared to rubber bushings, delivering more precise suspension feedback and improved chassis response.

For Subaru owners, upgrading to the Hardrace Pillow Ball Rear Toe Arm means gaining better rear-end stability during aggressive cornering and high-speed driving. The ability to adjust rear toe settings allows for tailored suspension geometry that can be optimized for different driving styles or track conditions. This direct bolt-on component maintains OEM fitment standards while elevating the handling dynamics of your WRX or STI.
