Hardrace Rear Trailing Arm Relocation Kit 2014-2021 WRX/STI | Corrects Rear Suspension Geometry | Suspension Upgrade
Overview
The Hardrace Rear Trailing Arm Relocation Kit is designed to enhance the rear suspension geometry of the 2014-2021 Subaru WRX and WRX STI models. By lowering the rear trailing arm mounting points by 45mm, this kit effectively reduces anti-squat, which translates into improved traction and stability during corner exit. This upgrade is ideal for Subaru enthusiasts seeking better handling balance and more confident weight transfer under aggressive driving conditions.
Engineered with precision, the relocation brackets are constructed from high-strength steel alloy and finished with an ED coating and paint for superior corrosion resistance and durability. Hardrace’s focus on quality materials and robust construction ensures these components withstand the rigors of spirited street driving and track use alike. This kit reflects a thoughtful approach to suspension tuning, addressing a common limitation in factory geometry for enhanced performance.
For Subaru owners, especially those who push their WRX or STI on twisty roads or track days, this relocation kit offers tangible benefits in cornering grip and vehicle stability. By optimizing the rear suspension’s anti-squat characteristics, drivers experience improved rear wheel traction and more predictable handling dynamics, making it a valuable upgrade for both street and performance applications.
