Tein Mono Racing Coilovers 2015-2021 WRX / 2015-2021 STI

Here, you are looking at the Tein Mono Racing Coilovers for the 2015-2021 WRX/STI.

Camber / Caster Adjustable Pillow Ball Mounts

For front strut suspensions, MONO RACING includes the camber and caster angle adjustable pillow ball upper mounts evolved from SUPER RACING upper mounts. Many upper mounts provide camber adjustment feature, but MONO RACING upper mounts are also caster adjustable. Camber angle can be adjusted steplessly while caster angle adjustment is available in 4 steps and both can be adjusted individually.*Except some models.

Selectable Spring Rates

Lower brackets on strut type suspensions come with camber angle adjustment feature. Camber angle can be adjusted by rotating the eccentric collar 180. This feature can enable camber angle adjustment, even if it can not be adjusted with the upper mounts. Both adjustments at the upper mounts, if applicable, and the lower brackets combined allows for total camber angle adjustment to meet various needs and preferences.*Eccentric collars with different offsets are available (optional).

Mono-Tube (Upright Strong Tube)

Mono tube structure of MONO RACING completely separates the oil chamber and the gas chamber and hence aeration does not occur. This enables stable generation of linear damping force, reacting to the finest changes in road surfaces, even when running aggressively and repeatedly on circuits. With this, superior-quality MONO RACING offers capability for the most delicate control of the vehicle and for the deepest level of communication with the roads.

Full Length Ride Height Adjustment Advance M.S.V

MONO RACING uses "ADVANCE M.S.V." for damping force adjustment feature. "ADVANCE M.S.V." combines "M.S.V." mechanism to finely control damping force in micro speed range with "ADVANCE Needle" to widen the damping force adjustable range, for superior steering response and traction performance, fully utilizing the damping force adjustable range.

Damping Force Adjustment

MONO RACING features 16-level damping force adjustment, for simultaneous adjustment of compression and rebound. Modify ride comfort and handling according to your preference, changing the properties of the shock absorber with the adjustment dial.
Compatible with EDFC Series

With EDFC (Electronic Damping Force Controller) series installed, damping force can be controlled from the cockpit with ease.

Stepping motors attached in place of adjustment knobs control the damping force quickly and accurately.

Use of EDFC turns 16-level adjustment into finer 32-level or 64-level adjustment mode (64-level only available with EDFC ACTIVE / EDFC ACTIVE PRO), to provide the optimum performance by fully utilizing the damping force adjustable range drastically widened by the use of "ADVANCE Needle".

With EDFC ACTIVE / EDFC ACTIVE PRO, damping force can be controlled automatically according to changes in G-force and/or vehicle speed, to offer a very smooth and slick ride like never before.

Some models are NOT compatible with EDFC series.
