Öhlins Road & Track suspension systems are engineered to
provide the ideal balance of track capability and street comfort. We utilized
40+ years of experience in the motorsport and OE industries to produce a
package incorporating patented technology with OE levels of quality and
longevity. We then apply our tuning philosophy to each particular application
to extract the most performance while 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.
