BMW 3 Series E21: Street R1 Dynaparts Coilovers (75-83)

On VW and Honda forums, the question comes up often: which coilover lets you go from daily driving to the track without taking the kit apart each time? The answer is the Street R1 Dynaparts: 1-way, 33-position adjustment, ride height separate from damping, and springs calibrated to handle track corners as well as Tuesday morning roundabouts.

Why choose the Street R1?

The Street R1 is designed for the enthusiast who wants a genuine, refined coilover kit without sacrificing daily comfort. Separating ride height from damping lets you lower the body to your liking without unnecessarily stiffening the ride. For 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 competition-level control. The Track R2 and R3 versions are reserved for exclusive track use with inverted monotube architecture.
