Dynaparts ranges: what's the difference between Street R1, R2, R3 and Track R2, R3?

The Dynaparts coilover range comes in five levels, from the versatile daily/track kit to the full racing kit designed exclusively for circuit use.

Street R1 (1-way)

Damping adjustment on 1 way: compression and rebound adjusted simultaneously via a single knob, 33 positions. Designed for daily driving and occasional track days. Standard design, separate oil reservoir. Top mounts included depending on application.

Street R2 (2-way)

Independent 2-way adjustment: compression and rebound tuned separately to fine-tune behaviour under braking, in corners and on corner exit. 33 positions per way. Designed for daily driving and track use. Standard design, separate oil reservoir.

Street R3 (3-way)

Independent 3-way adjustment: rebound, low-speed compression and high-speed compression. 33 positions per way. Maximum precision for fast chicanes and varied surfaces. Designed for daily driving and competition. Standard design, separate oil reservoir.

Track R2 (2-way, inverted design)

Inverted monotube design, separate oil reservoir and additional reservoir. Independent 2-way adjustment, 33 positions per way. Circuit use only. High spring rates to handle track loads.

Track R3 (3-way, inverted design)

Inverted monotube design, dual reservoir, full 3-way adjustment, 33 positions per way. Total control over suspension kinematics. Circuit use only. Maximum precision for serious lap timing.
