Why choose the Street R1?

The Street R1 is designed for the enthusiast who wants a true filtered coilover kit without sacrificing everyday comfort. Separating ride height from damping lets you lower the body to your liking 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 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 inverted monotube architecture.
