Add to Wishlist


The Street Flex damper is the evolution of Tein's popular Type Flex coilover for your Honda Civic and Civic SI. 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 their new Advance Needle technology and new damper valving specs, giving the driver a much more noticeable feel in damping force change and control.

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.

Note: Non-Si models require Tein's M14 bolt conversion kit for installation. Part # SPS12- P9043

Spring Rate: 392 ft-lbs Front/448 ft-lbs Rear

Ride Height Adjustment Range: -1" to -2.2" Front/ 1.1" to -2.8" Rear
