TEIN Street Basis Z Coilover Kit Subaru Impreza WRX | STI 2008-2010

The Tein STREET BASIS Z Coilover System combines affordability and comfort packaged into a masterfully constructed suspension system. These coilovers utilize a Twin-Tube setup that when compared to the regular mono-tube systems, these twin-tube systems attain longer stroke with a smaller repulsive force, resulting in increased ride comfort. Thanks to this unique characteristic, you can negotiate gaps and bumps steadily on rough roads, meaning a smooth ride at low speed and stability at high speeds.
