Tein USA
Super Street With Pillow Ball Upper Mount
'08 And Newer Subaru WRX
The 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 dragstrip, local circuit, or Autocross course. It includes both ride height and 16 levels of damping force adjustment to allow the driver to dial in the suspension for various road conditions, adding front and rear upper mounts. The upper mounts increase steering response and allow for EDFC compatibility. On strut-type vehicles, the front upper mounts will include camber adjustment plates.

Equipped with separate ride height and spring preload adjustments, the driver is able to set up the suspension to meet both advanced street and track conditions. Other features include 16-way damping force adjustability, which is EDFC compatible, and a special Teflon coating to prevent corrosion.
