Öhlins has been an integrated part of the Motorsport industry for over 40 years. With its headquarters in Sweden, there are over 320 employees and a test center at the most demanding track in the world, the Nurburgring. Öhlins is the choice of Professional racers from Touring Cars, 24 Hours of LeMans teams, and the new 2018 BMW M4 GT4 factory racecar.
The 3DM Motorsport "Road Sport" suspension kit is based on the Öhlins "Road and Track" lineup which provides optimal suspension performance on both the street and the track. You like stiff and reactive? Or soft and forgiving? It’s all there. 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 from the truth. Just a few clicks either way will soon have your car responding precisely to your inputs and driving style.

3DM Motorsport BMW F8X M3/M4 Road Sport Specifications:
The Road Sport kit is focused more towards street comfort than ultimate track performance. Even though it is more comfortable on the street you can still enjoy this kit on the track and twisty back roads. At the same time we also took the opportunity to use Swift springs which allowed us to design the kit to allow for a more aggressive wheel/tire package that did not require wheel spacers to clear the front spring perch. Lastly, we add Swift spring thrust sheets to eliminate spring bind.
- Front Swift Spring: 80 N/mm (450 lb/in)
Rear Swift Spring: 160 N/mm (913 lbs/in)
One of the original issues with the base kit kit was that the rear spring would become loose on the spring perch if the ride height was too low. We fix this issue by internally modifying the damper to limit droop travel just enough to resolve the problem. This does not affect the suspension in any other way other than at full droop, IE when the car is on a lift.
Generally, unless there is a drastic spring change, the Öhlins dampers do not need to be re-valved. However, we found that a valving change to the rear damper of this kit really helped focus towards daily driver ride quality and brought the adjuster back to an appropriate adjustment range.
Includes original Öhlins 2 year warranty. This kit is fully serviceable and spare parts are available and can be found in our Spare Parts Catalog.
