Tein Street Flex Coilovers Mazda RX-8 SE3P 04+

The Street Flex damper is the evolution of the 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 the 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.

Additional Features:

Steel Construction
Twin Tube Internal Construction
Full-Length Adjustable via Threaded Body and Spring Seat/Seat Locks
16-Way Damping Adjustable (simultaneous compression and rebound)

Roadstersport II was a great purchase, easy install, and sounds great.

I red'all the parts in the order I placed and installed them in my car yesterday. I am beyond happy. The install went without a hitch. The results were fantastic. The new brakes track straight, make no noise, and stop the car authoritatively. The new rotors look pretty cool, which we all know isn't all that important, but having 6 women offer to bear your children, because your car looks SO cool is a good problem to have. Thank for great products and service.
