Description

The Öhlins Road & Track Coil Over system is specifically designed and valved for GR, GV, and VA chassis Subaru WRX and STI. With spring rates and valving specific to each application, this ensures high-performance capabilities on the track without compromising comfort during everyday driving.

Constructed of anodized aluminum, the overall weight is significantly less than factory components and is anti-corrosive. An inverted monotube strut with a floating internal piston makes it's construction more rigid than standard monotube designs and is less susceptible to lateral loads. Öhlins' DFV (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.


Why?

The Öhlins Road & Track suspension gives our customers a true racing experience, with their own cars, without losing comfort when commuting to work. Our unique Dual Flow Valve (DFV) technology allows you to quickly change the stiffness of the shock absorber. When arriving to the racetrack, just turn the golden knob clockwise on the damper to set it in race mode this action changes all four areas in the damper; low and high speed compression and rebound damping.

With Öhlins Road & Track coil overs you will experience a car with blistering response times, improved bump absorption and a massive amount of grip to increase the safety when driving your car on the limit. The car will be easier to balance on the edge of what the tires can handle before losing grip. You will be much quicker on track. The DFV suspension prevents you from losing the racing line when hitting bumps or curbs. The DFV components within react quickly and keeps you in control of the car and in contact with the track. When driving to and from the track, just set the dampers in road mode for a more relaxed and comfortable drive, still with more grip and quicker response time than ever before.

Details


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 strut than a coilover set-up. Over undulating surfaces, the compliancy of the R&T units allows the car to crest bumps and pot-holes, 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’s worth comparing how it’s 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 Öhlins method is to leave the spring seat in its perfect position, whilst 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’ve set it all up, the adjuster simply locks off to maintain your exact settings.

Dampers will get hot. That’s one thing that you can be sure of. As the piston moves within the damper, it generates friction – and therefore, heat. Although we can’t stop heat, we can deal with it, and this is yet another way that Öhlins differs from the competition. As the heat increases, the viscosity of the damper fluid can change, altering the car’s handling characteristics. Our unique needle bleed valve expands with temperature, closing the gap that the fluid travels through, maintaining a consistent damping rate. The best thing of all? You won’t even notice! All you’ll feel is that the car responds consistently, lap after lap, turn after turn. Allowing you to concentrate on braking points and apexes whilst the Öhlins technology takes care of the damping.

These kits all work well ‘out of the box’, but there’s still plenty of adjustment for you to set things your way. You like stiff and reactive? Or soft and forgiving? It’s all there. Too much low speed rebound damping can have an adverse effect on grip, so the easily accessible adjuster at the base of the Öhlins units allows small, but positive increments of fine tuning, so you can take into account every single parameter. Sounds complicated? Nothing could be further for the truth. Just a few clicks either way from our factory settings will soon have your car responding precisely to your inputs and driving style.

Most of the Road & Track McPherson struts also feature camber adjustable upper and lower mounts to give you the possibility to fine tune your wheels for the right occasion – whether you want to go for a ride in your neighborhood or take your car for a spin at the track on a weekend.
