Circuit Master Damper is tested through XYZ racing teams all over the world. 9720 ways of different adjustments can meet all customers’ needs and win the 1st place in every race.

Because its 3 adjustment knobs with small oil hole design, when driving through big bumps, the coilover oil will go through small passage which might cause some small noise. This is normal situation. This product is made for circuit tracks and there will be no concern for bumps on the tracks.

Top design for all types of suspension in the world.

Mono tube design.

Full ride height adjustable.

Not suitable for street use.

One year limited warranty; send back for repair.

External nitrogen reservoirs

With 3 adjustment knob: to adjust the dampening force of
rebound and compression separately is available.

All applications listed on our website are for 2WD model
unless we specify 4WD.

Aluminum Top Mount (A6061)

Each application comes with pillow ball upper mounts on McPherson suspension, which enables you to experience excellent handling. This cannot compare to the OE one. Most of pillow ball top mount on McPherson strut has camber adjustability.

Mono-tube Design

Mono-tube design is adopted for this suspension system as it can retain stable damping and have varieties of response to the road conditions. This larger piston diameter of 45mm. The shock body 45mm steel (STKMI3C) though precise process to get the highest performance and quality.

9720 Way Damping Settings

With the external nitrogen reservoirs, to adjust the dampening force of rebound and compression separately is available. 9720 ways of different adjustments can meet all customers' needs and win the 1st place in every race.
