Add to Wishlist


Tein's Basis coilovers for the Miata are an entry-level setup that feature ride-height adjustment but do not offer adjustable shock damping. Basis are valved for street use and are an affordable, balanced solution to purchasing shocks and springs or sleeve-type coilovers. Tein Basis feature a steel twin-tube design, with adjustable spring perches and utilize the OEM suspension mounts. Because the Tein Basis coilovers are a complete 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.
