BMW E36 3-series Track Line Stand-alone electronic suspension kit

Semi-active electronic suspension for track use. Stand-alone set includes control unit, touchscreen and wiring harness.

TracTive Stand-alone electronically-adjustable shocks have been developed to implement high-tech semi-active suspension in any car.

The dampers are fitted with the TracTive patented DDA (Dynamic Damping Adjustment) valve. With its reaction time of 6 to 10 milliseconds from full soft to full hard, it is one of the fastest damping adjustments in the market. It demonstrates a tremendous stability and reproducibility, and is rapidly becoming THE technology chosen by high-end OE and racing teams. For every application the damping level and damping adjustment range is set-up from factory. It is possible to tune the damping level if required.

The display allows you to tune the suspension to almost any application by controlling roll, pitch and dive motions of the vehicle. The motion of the vehicle is monitored by a g-sensor integrated in the control unit, which is installed close to the center of gravity of the vehicle. The calibration is set up in the factory and can be updated if required.

The stand-alone control system comes with a touch screen display that allows the driver to make on-the-fly adjustments, save settings and even make driver-specific setups. The driver is able to adjust the damping of the front and rear axle in 5 levels, but also the suspension resistance to roll, and pitch/dive in 5 levels. The display can be centrally mounted for easy access. The kit includes a remote knob that can be centrally mounted for easy access.

The hardware of these shocks is identical to the track kits, except that the manual rebound adjuster has been replaced by the internal DDA valve and a cable coming out of the piston rod side of the dampers. Its components and technologies are used in the highest racing categories. Each kit is engineered specifically for optimal performance and durability. The dampers are fitted with Eibach springs and have an infinite ride height adjustment, either through the platforms on the shock bodies or through the separate adjusters. TracTive consciously chooses the use of 46mm high flow pistons in various versions, low friction seals and 16 mm super finished, induction hardened, Q&T CrMo-steel piston rods for all shocks. Shock absorber bodies are made from hardened aluminum alloy to ensure thermal stability and light weight. For McPhersons TracTive uses a steel inverted strut design with 38mm high flow piston in various versions. This design guarantees minimum stiction and maximum construction stiffness by using bearings and components derived from the highest levels of motorbike racing.

All track kits are fitted with specific top mounts. Inverted struts are fitted with adjustable mounts (camber and/or caster) and non-McPherson shocks with solid top mounts.
