PRODUCT OVERVIEW
TEIN Dampers - Street Flex: The Street Flex damper is the evolution of our popular Type Flex coilover. Developed to provide the ultimate balance of comfort and performance for both street driving and circuit use, along with wide-range damping force adjustment using our new Advance Needle technology and new damper valving specs, giving the driver a much more noticeable feel in damping force change and controllability. The shortened shell case design provides optimum damper stroke at lower than standard vehicle ride height. Full-length adjustability offers separate spring preload and ride height adjustment. Updated internal components and external coatings increase durability and product life. Includes Pillowball Upper Mounts (camber adjustable for strut type applications) and is compatible with the EDFC and EDFC Active systems.
