Tein Flex Z Coilover '13-'24 Scion FRS/Subaru BRZ/Toyota 86/Toyota GR86

Part #: VSQ54-CUSS4

The Tein Flex Z for the FR-S features a full-length ride height adjustment system, enables adjustment of ride height by adjusting the case length, without changing the damper stroke length and/or spring pre-load. By adjusting the case length to change ride height, the ride quality stays optimal. A big advantage when the vehicle is used for street driving.

This system not only makes it possible to maintain a good balance between the lowered appearance and ride comfort, but also provides 16 different damping adjustments for the driver to enjoy.

The Tein Flex Z contains the ever-popular 16-level damping force adjustment (compression/rebound together) feature with the use of a needle valve. By turning the adjustment knob, damping force (stiffness) is adjusted linearly step by step. A quick and easy way to change the ride and handling of the car to suit driver's needs and preferences.

The Tein Flex Z lowers the front of the vehicle by -30 mm and the rear of the vehicle -30 mm instantly and can be further adjusted to be lower or higher depending on the driver's preferences.

The Flex Z coilovers also feature a 6 (kgf/mm) spring in the front and a 6 (kgf/mm) spring in the rear for the ideal match of spring to shock damping characteristics.


  • Spring Rate Front: 6 (kgf/mm)/ 336 (lbs/in)
  • Sring Rate Rear: 6 (kgf/mm)/ 336 (lbs/in)
