Intrax 4 Way Coilover Suspension Systems for the Toyota Yaris GR Gen 1 & Gen 2 2020 to Present

The 4-Way shock absorber is Intrax’ top-rated product. The damping can be adjusted separately for the low-speed bump (inward damping), the high-speed bump and the rebound (outward damping) of the shock absorber. You can also adjust the total compression range. The 4-Way shock absorber is based on the same technology that has helped Schumacher become a World Champion. The interior is more comprehensive than that of all other Intrax dampers and contains more than 115 precision parts.

– The slow inward damping (also known as ‘low-speed compression’) determines, overall, the front to back and left to right movement of the car (also known as ‘pitch’ and ‘roll’). These movements are the result of acceleration, braking and cornering speed.

– The fast inward damping (also known as ‘high-speed inward compression’) determines, roughly speaking, the compression of the wheels on short bumps, such as curb stones and rills in the road surface.

– The outward damping (also known as ‘rebound’) stabilises the car, damps the unwanted movements and absorbs the unwanted energies.

Large diameters
Where possible, the housing of the 4-Way shock absorber is made of high-quality aluminium (if desired or required, it can also be made of steel). This guarantees a low weight, maximum strength and optimal cooling. Whilst designing the 4-Way shock absorber, the largest possible diameter is chosen for an even more accurate control of the damping; usually a 52mm housing with 46mm piston. Where possible, Macpherson struts are fitted as upside-downs with a 45mm diameter instead of a thin piston rod that is mounted to the chassis.
