If you are looking for a substantial upgrade over the stock end links but perhaps may not need and adjustable option, the Whiteline solid alloy front end links for the 04-07 STI may be for you. Constructed from anodized aluminum, Whiteline solid alloy end links feature upgraded polyurethane bushings for increased stiffness without the harshness or noise sometimes associated with spherical links. An excellent choice for a stout daily driven STI that may see laps around the Auto-X course from time to time.
