The COBB Tuning Stage 1 Suspension package is a one stop solution for your vehicle?s suspension needs. Emphasis is placed on eliminating body roll and maintaining a comfortable ride quality. Chassis rigidity is enhanced using our Rear Strut Tower brace while the front and rear Sway bars help reduce body roll and under steer. This is a well rounded package for anyone looking to carve a corner, navigate a chicane or just have a firmer suspension feel than factory specifications. Subaru Impreza STi 2004-2007
