Developed and modified for Group N and R4 rally classes.
The new rally class R4 was created to make Group N machinery competetive against the S2000 cars.
For this new class Öhlins has developed the Group N dampers to also suit the Subaru and Mitsubishi R4 cars.
The front strut is a Twin Piston McPherson strut with a 44 mm diameter piston, three way adjusted with one-way rebound and two-way compression. The rear damper is a Twin Tube TTX44 with a 44 mm piston and it's four-way adjusted.
Both front and rear are fully pressure balanced, eliminating the risk of cavitation and due to low gas pressure they keep the internal friction low.
