TracTive Suspension-BMW-E85-E86 – Z4 non-M-Semi Active Suspension-Road Track Line


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



ACE Active Controlled Electronics
Our standalone ACE systems gives you independent damping control. You can adjust roll and pitch interference for stable braking, controlled corner entry and after hitting the apex precisely, a better acceleration out of the corner. Curbstones and road undulations are perfectly managed by each individual damper.

Inside each ACE damper is our patented Dynamic Damping Adjustment (DDA) valve. This DDA valve is controlled by a sensitive multi-axis g-sensor and advanced algorithms developed from decades of racing and road testing. A dynamic proportional valve operating as a bypass has capacity for a large range of damping adjustment, and is capable of responding within only 6-10ms.

TracTive DDA, the world’s fastest valve!

Considering the human brain reacts within 150ms, you realise what a gamechanger the TracTive ACE system is compared to all conventional suspension systems.

ACE has the intuitive ability to react to changing road surfaces and conditions. Bumps and compressions are absorbed before you have the chance to notice them. Especially on track through a series of high-speed curves this makes it possible to hold the line without deflection.

Grip levels in all conditions are vastly improved, maximising each tyres contact patch. This gives you the ability to push your car to limits you wouldn’t have thought possible, maintaining safer driving. Electronic damper settings are completely adjustable on your touchscreen, ranging from full road compliance to controlled aggression on track. This is all within reach for you as the driver through the touchscreen display. Five individual settings can be saved which allows you change the setup of the car within seconds.
