Intrax 1k2 Coilovers BMW F8x M3 M4 F87 M2 M2 Competition

If it involves a Macpherson suspension, the absorber will feature a design with a 45mm Ø upside down insert. This upside-down design delivers a much higher installation rigidity (less flexibility) to the Macpherson suspension. This higher installation rigidity results in much better handling and more direct steering behavior.

Setting
All shock absorbers that Intrax manufactures are custom-built. This means the shock absorbers will only be manufactured once the specific data of the car (tyre type, use of the car, any adjustments made to the car, etc.) and the driver’s wishes are known. Based on these data, the engineers calculate/design the ideal shock absorber, which will then be manufactured.

Adjustable damping
Due to the larger diameter of the 1K2’s piston in comparison with the RSA, the adjustment can be even more refined. Unlike many competitors, Intrax deliberately opts for a single knob for the adjustment of the damping. With this single knob, you can adjust the bump (inward stroke) and rebound (outbound stroke) at the same time, in the proper pre-programmed ratio.

Thermostat
The 1K2 damper is fitted with an internal thermostat. The thermostat keeps the damping constant at varying temperatures. This means the damping and driving behavior remain exactly the same at various operating and ambient temperatures.

Large diameters
Where possible, the housing of the 1K2 shock absorber is made of high-quality aluminum. This guarantees a low weight, maximum strength and optimal cooling. Whilst designing the 1K2 shock absorber, the largest possible diameter is chosen for even more accurate damping control; usually a 52mm housing with 46mm piston. Where possible, Macpherson struts are fitted as upside-downs with a 45mm (52mm for the XL version) diameter instead of a thin piston rod that is mounted to the chassis.
