Öhlins DFV Road & Track Suspension Upgrade for G2X BMW 3 Series and 4 Series

Öhlins Road & Track suspension systems for the BMW 3, 4 Series (G2X) RWD/xDrive are engineered to provide the ideal balance of track capability and street comfort. We have utilized over 40 years of experience in the motorsport and OE industries to produce a package that incorporates patented technology with OE levels of quality and longevity. Our tuning philosophy is applied to each particular application to extract the most performance while still maintaining ride quality. One way Öhlins achieves this balance is our patented Dual Flow Valve. The DFV provides an additional oil bypass when bumps get severe. Engineers can tune the damper for increased support when turning and braking while maintaining composure over track curbing and rough pavement. This technology allows the use of linear spring rates (just like a motorsport application) for further chassis support without affecting daily comfort. Another feature is the damping adjustability via a single “clicker” knob that proportionally increases compression and rebound damping to best suit the driver’s needs. Whether it’s a smooth track or a weekly commute, the dampers can be adjusted within their usable range to best suit track or street conditions. In other words, an engineering degree isn’t necessary each time an adjustment is necessary. The BMW F82 M4 front shocks utilize monotube DFV struts with separate spring preload and height adjustment.  For the rear, inverted, aluminum DFV shocks come with height adjustable spring perches. Separating spring preload from height adjustment allows precise height adjustment without affecting suspension travel. Considering the F82 M4 is already tuned as a high performance street car with track capability, Öhlins took the approach most drivers will utilize track-oriented tires and tailored the suspension to match. The tuning approach minimizes understeer without the necessity of aggressive alignment settings or wide front tire fitments, while still maintaining safety and comfort on the street.

What is the DFV and how does it benefit the G2X 3 and 4 Series? DFV stands for Dual Flow Valve; a patented Ohlins technology that provides an additional oil bypass when bumps become severe. On the G2X platform, this allows the damper to be tuned for increased support during cornering and braking while maintaining composure over track curbing and rough pavement, without sacrificing everyday ride comfort.

Does this kit work on both RWD and xDrive G2X models? Yes. The Ohlins DFV Road & Track coilovers are compatible with both rear-wheel drive and xDrive all-wheel drive variants across the G20, G21, G22, and G23 model range.

How is the damping adjusted on the G2X Ohlins kit? Damping is adjusted via a single knob that proportionally increases both compression and rebound damping together. The adjustment range covers both track and street conditions without requiring complex or separate settings each time driving conditions change.

Is the Ohlins DFV a good fit if I use my BMW 3 or 4 Series for both track days and everyday driving? Yes. The Ohlins DFV Road & Track coilovers are built for that exact combination. Run the dampers in a street-oriented setting for the daily commute and adjust to a firmer track setting when you arrive at the circuit, with no extra hardware required.
