Ohlins x Turner Motorsport Street Tuned DFV Coilover System - 15-20 BMW M3/M4/Comp/CS
Tax excluded. Shipping calculated at checkout
The folks at Turner Motorsport have teamed up with Ohlins to bring the ultimate street coilover to the F8X community. Working alongside the engineers at Ohlins, they have developed a special recipe derived from the standard Ohlins DFV Road and Track kit for F8X. This Street-Performance system includes modified spring rates and valving for a more streetable coilover experience. If you are looking to enjoy your S55 car to the fullest, but don't want to forgo any ride quality, these are the perfect option.
Ohlins Racing has a long history dating back to 1976 of providing premium motorcycle and automotive suspension systems to numerous racing teams, individual racers, and OE brands such as BMW Motorsport, Audi, Lamborghini. Pagani, Ducati and Kawasaki. Over time, thanks to extensive R&D, testing, and tuning, their products have evolved into some of the highest quality suspension systems in the world, providing years of flawless operation on both the street and the track.
These kits provide an incredible feel over the bumps and dips in the road, without any of the discomfort you might have with a track-focused coilover kit. The DFV maintains comfort and agility by giving the same characteristics for both rebound and compression, allowing the wheel and tire to maintain constant contact with the road for maximum control.
The Dual Flow Valve works by controlling shock fluid flow based on resistance and impact velocity. This is controlled in both compression and rebound, giving the quick shock operation that helps maintain traction. At low shaft travel speeds, oil flows mostly through the shaft jet bleed. At higher shaft speeds, oil flows mostly through the compression/rebound ports in the piston. At very high shaft speeds, or during sudden accelerations from potholes or large bumps in the road, oil can then escape through the ports in the DFV, absorbing a large amount of energy that would otherwise throw off the balance and control of the vehicle and keeping the tire planted firmly on the ground. With all three compression and rebound ports working together according to pressure and shaft speed, the result is the notorious premium suspension feel that only Ohlins can offer.
In addition to managing the rebound and compression control, coilovers must also properly address heat changes in the shock oil. As the shock is pushed harder and longer, the oil quickly heats up due to friction and compression, and the oils flow characteristics change. The hotter the oil is, the easier it is for it to travel through ports and valves. To prevent this typical fade in control, Ohlins has implemented a temperature controlled needle bleed valve system that will expand as temperatures rise, slowly increasing restriction in the fluids flow through the valve gap. This produces a consistent dampening rate that maintains the vehicle's suspension characteristics no matter how hard you push your suspension's capabilities.
