If you need your Scion tC slammed, the Tanabe Sustec DF210 lowering springs are for you! These springs offer an aggressive spring rate and drop while still giving your car a great ride. Designed to lower your vehicle as much as physically possible, this system features Tanabe's Sustec 210 technology, a unique manufacturing process designed to produce superior strength and durability. Tanabe Sustec DF210 lowering springs offer a drop of up to 2.5" (depending on application) and will increase handling and stability as an effect of a stiffer spring rate and reduced center of gravity.
