Product Description

The Street Advance damper is the evolution of our popular Super Street coilover. Developed to provide a sporty ride feeling and aggressive stance, along with wide-range damping force adjustment using our new Advance Needle technology, giving the driver a much more noticeable feel in damping force change. The shortened shell case design provides optimum damper stroke at lower than standard vehicle ride height. Vehicle ride height is adjustable via the ZT coated threaded sleeve. Updated internal components and external coatings increase durability and product life. Street Advance dampers are great for daily driving and spirited driving for all types of drivers.

Made in Japan under strict quality control standards and developed by highly trained suspension engineers.
