TEIN TEIN Super Street damper kit was designed for drivers seeking improved handling on the street and at the track. A shortened shell case is utilized to allow the most piston stroke possible, which allows for a better ride at lowered ride heights, and increased grip at the track. Great for daily driving and occasion track use, whether it be at the drag strip, local circuit, or Auto-X course. Includes both ride height and damping force adjustment to allow the driver to dial in the suspension for various surface conditions.
