Why choose the Track R2?

The Track R2 is designed for drivers who use the track regularly and need a kit that lasts under repeated loads. The inverted monotube architecture improves lateral rigidity and heat dissipation. The twin oil reservoirs keep temperatures stable even during long sessions. Two independent channels to fine-tune compression and rebound depending on the circuit.

If you are looking for even more control, the Track R3 adds high-speed compression as a third channel. For mixed road/track use, the Street R2 and R3 offer the same fine-tuning in a daily-use format.
