RACEOPT RO-PDS-HR-2531 Progressive Dynamic High Response Coil Springs Blue 4pcs  [RO-PDS-HR-2531]

RACEOPT progressive springs for steadier handling

The RACEOPT Progressive Dynamic Spring - High Response is crafted to provide a reliable mix of compliance and support for sharper vehicle feedback. These springs are well suited to modellers who want predictable suspension behaviour under varying loads.

Variable tension for consistent grip

These blue springs cover a progressive tension span from 2.5 to 3.1, giving gradual stiffening as the spring compresses. The result is improved traction and reduced harshness when encountering larger impacts.

Engineered wire thickness and balance

Produced with 1.4mm line thickness and matched top and bottom symmetry, the springs focus on durability and consistent performance across repeated runs.
