Tein | Coilover Kit Flex A - WRX / WRX STi

Tein Coilover Kit - Flex A

TEIN FLEX A is equipped with new feature "Hydraulic Bump Stopper (H.B.S.)" which has been tested and proven effective in the world's harshest motorsports including World Rally Championship and European Rally Championship. When a lowered vehicle goes over big bumps, urethane or rubber bump stopper often causes a big upward jolt and/or rebound and can disturb controllability. On FLEX A, H.B.S., mounted inside the shock absorber, effectively generates damping force near and/or at full-bump, to absorb big impact smoothly. Comfortable ride in vehicles even at full occupancy will revolutionize the industry.

When Hydraulic Bump Stopper is not actuated, the valve is floating and is not blocking the oil flow through the base valve. Damping force is generated just as same as the shock absorber without H.B.S. through the base valve port and the friction of stacked shims. Once the piston rod strokes further than the certain point, the valve is pushed down to activate H.B.S. The port is made narrower, limiting the oil flow, to generate high damping force only near and/or at full-bump.

The relief valve installed suppresses the sudden rise in damping force, when the inner pressure exceeds the certain level.

By changing the components, operating point and/or damping force specification of H.B.S. can be modified to optimize the settings for wide variety of vehicle models.

Ordinary shock absorbers have to have bump rubbers to avoid damages from bottoming out. Impact from hitting the bump rubber is huge and the energy accumulated by compressed rubber is released as repulsion force, causing unstable behaviors. With H.B.S., such impact is absorbed and converted to thermal energy inside the shock absorber, minimizing the shock and eliminating repulsion force.
