Whiteline KTA123 Rear Adjustable Control Arm Kit - Camber/Toe for 2004-2007 Subaru Impreza WRX STI

Fits 2004-2007 Subaru Impreza WRX STI.

The Whiteline KTA123 is a comprehensive kit of four adjustable control arms engineered to replace the factory rear lateral links. This kit provides a precise solution for modifying rear camber, toe, and track width, allowing for up to 50mm of adjustment range. By replacing high-compliance factory bushings with low-compliance synthetic elastomer units, this kit significantly reduces suspension flex and improves the direct connection between the chassis and rear suspension for more predictable handling.

Constructed from high-strength steel with a protective powder-coated finish, these arms are designed to withstand heavy track use and harsh road conditions. The integrated internal grease reservoirs ensure the bushings remain self-lubricating for long-term friction management and noise-free operation. This kit is essential for correcting alignment geometry on lowered vehicles and optimizing the tire contact patch under cornering loads.
