2012-2019 BMW F8x - M2-M3-M4 Track Line - Plug&Play electronic suspension kit | TRAC-BW-Axx41

TracTive Plug & Play electronically-adjustable shocks have been developed as a high-tech electronic, replacement suspensions for a car fitted from factory with specific electronic suspension systems. 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. Although the valve is a lot faster, more stable and more reproducible than ZF CDC (found in many BMW EDC) and Bilstein Damptronic (e.g. found as PASM in Porsches), the DDA valve has similar electrical and functional properties and can replace these OE valves without losing its functional benefits. The Plug & Play system is a direct replacement for the original dampers, it plugs in with the same connectors and the dampers are controlled the same way as the original dampers. No delete kit required, no more fault messages in the onboard controls! 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 The hardware of these shocks is identical to the track kits, except that the manual rebound adjuster has been replaced by the internal DDA valve and a cable coming out of the piston rod side of the dampers.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.
