The Öhlins Dedicated Track Monotube Suspension Package for the BMW 3 Series (E9X) is a pre-tuned, bolt-on track suspension system built for drivers competing in spec racing classes and circuit events. Developed using Öhlins' Dual Flow Valve (DFV) technology and paired with Swift springs manufactured to Öhlins specifications, this package delivers precise, repeatable handling at the limit. Each application is shake-rig developed and track validated, with specific spring rates, damper click settings, and ride height specifications established to suit the chassis — no guesswork required at the track.
The DFV system allows fluid to flow efficiently in both compression and rebound phases. At low shaft speeds, fluid passes through the bleed circuit for controlled damping. As shaft speed increases, flow transitions through the piston ports, and under high load or sudden impacts, the DFV opens to allow additional flow. This results in improved bump absorption, increased traction, and reduced harshness — critical for maintaining speed and consistency through extended track sessions.
Öhlins' temperature-reactive needle bleed valve compensates for changes in fluid viscosity as damper temperatures rise during sustained track use. This ensures predictable handling and repeatable lap times, even in the most demanding conditions.
Ride height is set to a target reduction of approximately 15mm front and 10mm rear from factory height, providing an optimal platform for track alignment without compromising suspension travel.
