Tein Street Advance Coilovers, an evolution of the Super Street, offer the same ride-height adjustability of the Basis but also feature 16-setting damping force adjustment for increased tuneability. Designed for street use, Tein Street Advance coilovers can be stiffened or softened and raised or lowered to meet any of your day-to-day demands. SS coilovers are designed specifically for the US market, so fitment and quality is perfect every time. The Tein Street Advance kit features twin-tube shocks, standardized straight springs, and steel construction for durability and quality. The kits can also be rebuilt and revalved by Tein, making them a complete long-term suspension solution. The Street Advance coilovers utilize the OEM upper mounts for simple installation.
