Tein Street Basis dampers are an evolution of the popular Basic coilover featuring updated internal components and external coatings for increased durability and performance. Made in Japan under strict quality control standards and developed by highly trained suspension engineers, Tein's new Street Basis coilovers for the Mazda Miata are an entry-level setup that feature ride-height adjustment but do not offer adjustable shock damping. Street Basis are valved for street use and are an affordable, balanced solution to purchasing shocks and springs or sleeve-type coilovers. Street Basis coilovers are a complete twin-tube design setup, they offer increased stroke over a stock-type setup or spring and shock package, which increases shock life and prevents the 'bottoming out' associated with traditional lowering springs. This kit is also completely rebuildable, making it a suitable long-term solution for most styles of performance street driving.
