02-07 Subaru WRX & STI Tein Coilovers

Street Basis Coilovers

Tein Street Basis dampers are an evolution of the popular Basic coilover featuring updated internal components and external coatings for increased durability and performance. Made in Japan under strict quality control standards and developed by highly trained suspension engineers, Tein's new Street Basis coilovers for the Subaru WRX & STI are an entry-level setup that feature ride-height adjustment but do not offer adjustable shock damping. Street Basis are valved for street use and are an affordable, balanced solution to purchasing shocks and springs or sleeve-type coilovers. Street Basis coilovers are a complete twin-tube design setup, they offer increased stroke over a stock-type setup or spring and shock package, which increases shock life and prevents the 'bottoming out' associated with traditional lowering springs. This kit is also completely rebuildable, making it a suitable long-term solution for most styles of performance street driving.

Street Flex Coilovers

The Street Flex damper is the evolution of Tein's popular Flex coilover. Developed to provide the ultimate balance of comfort and performance for both street driving and circuit use, along with a wide 16 way range of damping force adjustment using their new Advance Needle technology and new damper valving specs, giving you 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 which is beneficial for optimum performance and corner balancing. Updated internal components and external ZT 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.

Mono Flex Coilovers

Mono Flex coilovers are designed for those looking for the best performance on the street and track. They are very similar to the Tein Flex coilovers featuring full ride height adjustment and 16 levels of damping. The major difference is the mono-tube internal damper design. This allows quick heat dissipation for consistent handling and a larger damping range as well. Tein Mono Flex coilovers include upper mounts, and are also fully rebuildable, making them a complete long-term solution for your high performance Subaru.

Electronic Dampening Force Controller


This optional product makes it possible for the driver to control the damping force by controlling a motor installed in the shock absorber while being seated in the driver's seat. Since the damping force can be manually controlled with ease to meet different situations, the driver can enjoy variations in the suspension setting. Go from living your life a quarter mile at a time to Sunday cruising at a buttons press. The EDFC can control the 16 different stiffness settings and can also be put into 32 setting mode which adjusts in half-step increments for the purists and control freaks. The compact (approximately 3.5" wide x 1" tall x 4" deep) control box is easy to mount, making it a great add-on.
