Why choose the Street R1?

The Street R1 is designed for the enthusiast driver who wants a genuine coilover kit without sacrificing everyday comfort. Separate ride height and damping adjustment lets you lower the car to your preference without making the ride unnecessarily harsh. For first track days, the R1 offers a solid foundation with its remote reservoir and 33 damping settings.

For more advanced setups, the range extends to the Street R2 (2-way independent) for those who want to fine-tune compression and rebound separately, and the Street R3 (3-way) for motorsport-level control. The Track R2 and R3 versions are reserved for exclusive track use, featuring an inverted monotube design.
