The DFV Technology Advantage. So what is DFV? It is Dual Flow Valve technology and it sets Ohlins apart from competitors. Only Ohlins has DFV technology on its road and track products. With DFV, the dual flow valve gives the same characteristics on rebound as it does on compression, thanks the damper fluid having a consistent path of flow in both directions. This means that the wheel and tire can quickly and effectively resume their important position back on the ground, providing grip and traction. The new Ohlins Road and Track range uses DFV technology on every single fitment, making it the perfect upgrade for the enthusiast that needs comfort and agility in the one unit.

Figure 1: (Compression flow) At low shaft speeds, oil flows mostly through the shaft jet bleed (lower dotted arrow). At higher shaft speeds, oil flows mostly through the compression ports in the piston (upper dotted arrow). At very high shaft speeds, or during sudden shaft accelerations, oil can also escape through the compression ports in the DFV, increasing comfort. Figure 2: (Rebound flow) At low shaft speeds, oil flows mostly through the shaft jet bleed (lower dotted arrow). At higher shaft speeds, oil flows mostly through the rebound ports in the piston (upper dotted arrow). At very high shaft speeds, or during sudden shaft accelerations, oil can also escape through the rebound ports in the DFV, maintaining tire contact with the road. Because DFV opens more quickly and easily on minor road imperfections, ride comfort is surprisingly supple and more akin to an OEM shocks than a coilover set-up. Over undulating surfaces, the compliance of the Road and Track units allows your Miata to crest bumps and potholes, whilst still keep stable and in control. Traction is always maintained at its optimum level. When comparing suspension, why settle for second best?

Figure 3: (Vehicle no DFV) Without DFV the oil can not flow through the piston quickly enough on the rebound stroke after hitting a bump, so the tire is not able to stay in contact with the road.

Figure 4: (Vehicle DFV technique) The DFV valve opens, letting the oil flow quicker through the piston on the rebound stroke after hitting a bump, enabling the tire to stay in contact with the road. When adjusting ride height on coilover units, it is worth comparing how it is done. On many inferior designs, height is adjusted by raising or lowering the lower spring platform. This has the effect of compressing or extending the spring, which can limit the suspension travel that may cause topping out. The Ohlins method is to leave the spring seat in its perfect position, while the lower flange spins easily on the threaded body, to allow you to adjust with absolute precision whilst maintaining the perfect characteristics that we took so long to design in! Once you have set it all up, the adjuster simply locks off to maintain your exact settings.
Dampers will get hot. That is one thing that you can be sure of. As the piston moves within the damper, it generates friction and therefore, heat. Although we cannot stop heat, we can deal with it, and this is yet another way that Ohlins differs from the competition. As the heat increases, the viscosity of the damper fluid can change, altering the car handling characteristics. With Ohlins a unique needle bleed valve expands with temperature, closing the gap that the fluid travels through, maintaining a consistent damping rate. What you feel is that the car responds consistently, lap after lap, turn after turn. Allowing you to concentrate on braking points and apexes whilst the Ohlins technology takes care of the damping.

These kits amazing out of the box, but there is still plenty of adjustment for you to set things your way. You like stiff and reactive? Or soft and forgiving? It is all there. Too much low speed rebound damping can have an adverse effect on grip, so the easily accessible adjuster at the top of the Ohlins units allows small, but positive increments of fine tuning, so you can take into account every single parameter. Sounds complicated? It is actually very easy to adjust a few clicks either way to find the settings that work for you.
Since 2010 super light-weight design with a majority of the parts in aluminum and on top of that all shocks have proven through extensive corrosion tests according to ISO 9227.
