GT Lowering Springs Fits Scion tC 05+ Ksport GT lowering springs have been designed to give your car superior handling with an aggressive race look. Most other brands use a linear rate, but Ksport utilizes a progressive rate for several reasons. A progressive rate allows a plush comfortable ride under normal travel, but since the rate shifts higher during compression, it stops "body roll" during heavy braking, hard acceleration, or fast cornering. By lowering the center of gravity from OE height you dramatically improve performance and handling characteristics. Features: Progressive rate design, High tensile chrome silicone wire, Cold wound for strength, shot peened for increased stress relief, Aggressive drop while retaining superb handling characteristics DROP: 2.0 (F) 1.75 (R)
