Why choose the Street R1?

The Street R1 is built for the enthusiast who wants a genuine coilover kit without giving up everyday comfort. Separating ride height from damping lets you lower the car to your liking without needlessly stiffening the ride. For your first track days, the R1 offers a solid base with its remote reservoir and 33 damping 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 track-only use with an inverted monotube design.
