NVH note: The RACE spring pack makes noise, particularly on sharp bumps. Not an issue on a dedicated track car, but on a street car this can be bothersome for some customers. If you’re concerned about NVH, email us to consult on which spring pack suits your needs best.
The ND Xida are developed with Tractive Suspension (Netherlands). Xidas can be ordered as double, triple adjustable or electronic damping adjustment. The exceptional valving sensitivity produces both incredible grip over any paved surface and exceptional ride quality. Despite the surprising streetability, these are purpose-built racing dampers intended for use under the most demanding motorsports environments. Damping adjustment at the top.

What is ACE?
ACE is Active Control Electronics. This is our Semi-Active suspension. The shocks are the same basic valving as the 1-way adjustable but include the Tractive DDA valve which can change damping across the full range in 6-10ms. For reference, the blink of an eye is 100-400ms. The system adjusts so fast that its actually much faster than a modern CANbus. Changes are made via the touchscreen programming keypad/display to your 5 presets. The control system has a 4 axis accelerometer that senses all movement to then adjust the shocks instantly. There is so much roll control available that for some setups, you can actually disconnect the sway bars. You get to tune front and rear roll stiffness, pitch and base damping values independently. Built to order, allow +6 8 week lead time.
