04-10 Mazda RX-8 Tein Coilovers

Basic Coilovers

Tein's Basic coilovers for the 04-10 Mazda RX-8 are an entry-level setup that feature ride-height adjustment but do not offer adjustable shock damping. Basics are valved for street use and are an affordable, balanced solution to purchasing shocks and springs or sleeve-type coilovers. Tein Basics feature a steel twin-tube design, with adjustable spring perches and utilize the OEM suspension mounts. Because the Tein Basic coilovers are a complete 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.

Flex Coilovers

Flex coilovers are designed to provide the ultimate balance between comfort and performance. They are a completely different coilover from the Basic/SS line, utilizing a fully threaded shock body that is adjustable both at the spring perch and lower shock body for independent height and spring preload adjustments. The twin-tube damper design makes for improved reliability and longevity. These are Tein's street/competition coilovers; they can be tuned for street use but will also be comfortable on the racetrack or autocross course. Tein Flex coilovers include upper mounts and are also fully rebuildable, making them a complete long-term solution.

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 RX-8.


  • Specs:
  • Spring Rate (Lb/In): F: 559 / R: 392

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.
