Point

“Natural steering feeling” so that a driver can trace the line as desired was pursued, and smooth cornering as STI's unique handling characteristic.
Focusing on driving stability during cornering to match the vehicle's characteristics, supple damper movement can stabilize the vehicle body movement so the tires can continuously contact even on rough road surfaces.
The stock rear suspension's stiffness was improved so driving comfort can be maintained under long-distance driving maintaining its sportiness.
Utilizing the helper springs in both front and rear dampers enables to secure the stroke of the extension side as possible.
