The Heart of the System: DFV (Dual Flow Valve) Technology

The ultimate advantage of Öhlins dampers over the competition is the patented Dual Flow Valve (DFV) system. In a conventional shock absorber, oil flow during compression and rebound is often asymmetrical, leading to compromises between grip and stability.

DFV technology is a game-changer:

• Flow Symmetry: The system ensures identical fluid flow characteristics in both directions of piston travel.

• Lightning-Fast Response: Because the oil flows through the valve in both directions, the wheel instantly returns to its original position after hitting a bump or track curbing, maintaining optimal contact with the surface.

• Traction and Control: DFV allows for a drastic increase in traction, which directly translates into handling confidence and faster lap times.

Thermal Stability: Why lap 10 is as fast as lap 1?

During intense track use, dampers generate enormous amounts of heat, which alters the viscosity of the oil. In budget solutions, this results in “suspension fade”-the car becomes increasingly unpredictable as the session progresses. Öhlins has solved this problem with an advanced needle valve. Constructed from materials with a specific thermal expansion coefficient, this valve automatically compensates for the oil flow as the temperature rises. The result? Damping characteristics remain constant, regardless of how hard you push the system on the track.

Setup Personalization

The Road & Track kit for the Mustang S550 offers integrated compression and rebound adjustment through a single, precise adjuster.

• For daily public road driving, we recommend a setting in the range of 10-15 clicks from the fully closed position.

• For track sessions, the system allows for a quick “stiffening” of the suspension, increasing stability and minimizing body roll.

The Ultimate Setup is Coming: Restomotive x Öhlins

A damper alone is only one piece of the puzzle. To fully unlock the potential of DFV technology, we are developing a complete suspension system that will soon join our lineup. We are fusing Swedish hydraulics with our own engineering:

• Restomotive Camber / Caster Plates: They allow for precise camber / caster adjustment, which is critical in the Mustang S550 to protect tire shoulders during aggressive cornering.

• Restomotive Control Arms: Our proprietary fully adjustable arms eliminate the deflection of factory rubber bushings, ensuring axial stiffness and consistent geometry under heavy loads.

• 3D CAD Integration: The entire system has been designed and verified in a digital environment, guaranteeing a perfect fit with the S550 chassis mounting points.
