Why choose the Street R1?

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

To go further, the range moves up 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, with an inverted monotube architecture.
