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.

Ohlins' latest automotive suspension system, the DFV (Dual Flow Valve) Road and Track Coilover Kit, has bridged the gap between comfortable stock suspension and track focused coilover kits. These kits provide a ride that glides over typical bumps and dips in the road, all without the typical hard rattle and harsh feel of usual coilovers, and turn in tight and maintain tire grip and traction in corners significantly better than stock suspension ever could. This is all thanks to the spring rate chosen and Ohlins and their signature Dual Flow Valve. 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/track 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 lap after lap, turn after turn, no matter how hard you push your suspension's capabilities.

Established in 1976, Ohlins Suspension stands as a prestigious brand, collaborating with notable OE suppliers like BMW Motorsport, Audi, Lamborghini, Pagani, Ducati, and Kawasaki. The DFV Road and Track Coilover Kit by Ohlins integrates state-of-the-art Dual Flow Valve (DFV) technology, setting itself apart in the market for exceptional traction, grip, and handling.

The DFV technology ensures consistent rebound and compression characteristics, swiftly realigning wheels and tires on the road. Offering a balance between comfort and agility, these coilovers maintain an OE suspension feel at lower speeds and deliver precise control at higher speeds or on uneven terrain.

Temperature management is critical for shock oil performance. Ohlins employs a unique needle bleed valve system that reacts to temperature changes, ensuring consistent damping rates regardless of temperature fluctuations, guaranteeing reliable performance.

Key Features:

• Lightweight aluminum construction
• Long-term corrosion resistance
• 30-level 1-way adjustable dampening
• OE fitment using stock vehicle upper mounts location
• Rebuildable design
• Threaded shock body for height adjustment
• Adjustable spring preload for customization
• Monotube damper construction
• 2-year limited warranty
• Approximately 15mm lower than stock
• ECS Insider Tip: Adjust suspension valves for hardness or softness as needed.

The öhlins EDC Cancellation Kit for Road & Track deactivates control lamps and error reports when electronically adjustable OEM suspension is replaced by a mechanical system. The cancellation kit is just plugged into the original suspension controls. No further programming is needed.

Included:

• 1 Cancellation Kit
• Installation material (if needed)
• Mounting instruction
