Why choose the Street R1?

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

To go further, the range extends to the Street R2 (2-way independent) for those who want to tune compression and rebound separately, and the Street R3 (3-way) for competition-level control. The Track R2 and R3 versions are reserved for exclusive track use with inverted monotube architecture.
