“Natural steering feeling” so that a driver can trace the line as desired was pursued as STI’s unique handling characteristic._x000D_
Focusing on driving stability during cornering to match the vehicle’s characteristics, the helper springs in the front and rear maintain the stroke amount on the extension side so the tires can continuously contact even on rough road surfaces._x000D_
Management of VPS improves the driving comfort and sportiness. Driving comfort can be maintained under long-distance driving much better than the stock suspension._x000D_
Utilizing the helper springs in both front and rear dampers enables to secure the stroke of the extension side as possible. _x000D_
