ST XTA plus 3 coilover suspension kit for the BMW M3 and BMW M4

An increasing number of ST suspension components are now available for the BMW M3 Sedan (F80) built from 2014 to 2018 and the BMW M4 Coupé (F82) built from 2014 to 2020. There is now also the ST XTA plus 3 coilover suspension on top of the ST height adjustable springs, ST wheel spacers, and the ST XTA coilover suspension with adjustable rebound.

Because of the wide range of separately adjustable compression and rebound damping, the ST coilover suspension allows almost any setup required road suspension setup.

Compared to the other ST coilovers, the ST XTA plus 3 allows the preset damper setup to be individually adjusted in various parameters in just a few steps. Because of the wide range of separately adjustable compression and rebound damping, the ST coilover suspension allows almost any setup required road suspension setup.

The continuously variable lowering range covered by the parts certificate for M3 (F80) and M4 (F82) is 15 to 40 millimeters.

Continuously adjustable lowering is of course also possible with the ST XTA plus 3 coilover suspension. According to the parts certificate, the M3 sedan (F80) and the M4 coupe (F82) can be lowered continuously between 15 and 40 millimeters on both axles.

The used KW dampers can be individually tuned in the low-speed and high-speed compression stage each with 24 clicks.
Each click noticeably changes the performance of the ST coilover suspension and the low-speed rebound stage is adjustable with 16 clicks.

With 24 clicks each, the low-speed and high-speed compression stage forces can be adjusted. The low-speed rebound stage can be set with 16 clicks. The adjustable rebound damping influences, among other things, how quickly the chassis rebounds when the suspension is compressed during load changes. Together with the spring rate of the suspension spring, the compression damping influences the immersion speed of the piston rod in the damper. In addition, the compression damping also affects the body's pitching and rolling movements as well as its turn-in behavior.

Like all ST height-adjustable springs and ST coilover suspension kits, the ST XTA plus 3 coilover suspension is part of the so-called "Make it Yours" program. The XTA plus 3 coilover suspension can be ordered in 18 different colors from specialist dealers and also directly from the suspension manufacturer. In addition, the springs can also be individually labeled. Optional spring packages are in preparation for the ST XTA plus 3 coilover suspension for the BMW M3 (F80) and BMW M4 (F82). These different springs are available with different spring rates in order to be able to adapt, for example, the ST XTA plus 3 to lightweight modifications of the car.

In the case of performance suspensions such as the ST XTA plus 3 coilover suspension, the specifications Low-speed and Highspeed refer to the speed of movement of the piston rod when immersing and retracting. Slow piston rod movements are typical steering maneuvers and, for example, braking before corners, while fast piston rod movements are caused by road irregularities due to bumps and transverse joints in the road surface. On the BMW M3 (F80) and BMW M4 (F82), support mounts on the front axle struts are an integral part of the scope of delivery. They make the steering even more precise than with normal strut mounts using rubber-metal elements. In addition, the ST strut mounts can also be used to adjust the wheel camber.
