Öhlins Rally 

Optimized for pavement and other hard sufaces.

The 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. The proven Group N technology has now been updated with new settings based on WRC experience and a WRC developed Dynamic Compression and Dynamic Rebound Control, DCC/DRC, for the front TPX dampers. The Twin Piston McPherson strut also has a reinforced outer tube in high strength steel with calibrated bushing seats. The rear TTX damper has an extruded cylinder tube that creates less damper hysteresis which means improved wheel control and traction on the rear axle.

Features

• Updated PDS (Progressive Damping System) for increased jumping performance and temperature stability, gravel only
• WRC developed SDR (Stroke Dependent Rebound) for improved traction, jumping performance and improved stability when cutting corners
• Reinforced outer tube in high strength steel with calibrated bushing seats

Rear TTX

• Extruded cylinder tube body with less damper hysteresis for improved wheel control and traction on rear axle
