The Öhlins Dedicated Track Monotube Suspension Package for the BMW E46 M3 is a pre-tuned, bolt-on track suspension system built for drivers who prioritize circuit performance. 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. The kit includes racing camber plates and spherical upper mounts front and rear, eliminating the compliance found in factory rubber mounts for sharper turn-in response and consistent alignment under load.
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 20mm from factory height. The rear includes a dedicated height adjuster providing 1.5mm of change per full rotation, allowing fine-tuning of rake and balance without altering spring preload.

Technical Resources
Notes
- Suspension components are non-returnable once installed
- Spherical upper mounts will transmit more noise, vibration, and harshness than factory rubber mounts — this is inherent to the design and expected for track-focused components
- The BMW E46 M3 was not equipped with factory electronic dampers — no cancellation kit is required
