Provides stability at higher speeds

The Tein Street Basis Z/Advance Z Coilovers are some of the best cost-effective and quality set of coil overs on the market. This is a great suspension system for those who want something more aggressive than lowering springs. The Street Basis coil overs supersede Tein's Basic coil over design made with improvements in design and performance. These coil overs feature steel construction with twin tube internal components. These components include a larger piston diameter for the front and rear struts.
