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.

BMW E92 M3 Performance Spring Set is engineered to elevate your driving experience by using increased spring rates that reduce body roll and enhance handling dynamics. This performance spring set lowers your vehicle's center of gravity slightly, providing a balanced stance without sacrificing daily driving comfort.

• Reduced Body Roll: Experience improved stability and control during cornering.
• Enhanced Braking Performance: Minimized dive under braking for more precise stops.
• Improved Grip: Better tire contact with the road for increased traction.
• Slight Lowering: Lowers the vehicle by approximately 1/2 inch for a sportier appearance.
• Durability: Springs are preset to prevent sag and are shot-peened for stress relief.
• Dinan Badge Points: Earn 2 points toward your exclusive Dinan badge.

For over 35 years, Dinan has led the way in BMW tuning, focusing on balanced performance that maintains the original driving feel of your BMW. Each part is meticulously developed, tested, and backed by a four-year, 50,000-mile warranty. As you enhance your BMW with Dinan's high-quality components, you move closer to earning the prestigious Dinan badge, a symbol of superior BMW performance.

Dinan Performance Springs are matched to your BMW's chassis and suspension components to deliver better handling and looks without sacrificing ride quality. Dinan BMW springs are carefully engineered to work within your car's suspension travel and to improve suspension geometry. Spring rates are slightly stiffer than stock and dialed in to reduce bodyroll. A stiffer suspension makes the car more fun to drive and the lower ride height improves the looks by reducing wheel-fender gap.

Dinan spring specs -

• F: -1/2" (12mm)
  
• R: 0" (0mm)

Fitment note: When used with stock shocks the Dinan Ride Quality Kit is strongly recommended. The Kit consists of shorter and stiffer bump stops and spring perches that work better with the lowered ride height of these springs. While not explicitly required, less than favorable ride quality and handling may result without them.
