RACEOPT 1:8 GT High Response Progressive Dynamic Springs (Orange: T3.2~4.2, 2pcs) - Progressive Circuit Springs  [RO-GT-PDS-HR-32~42]

Tune Your 1:8 GT with RACEOPT Progressive Springs

Designed for 1:8 GT model setups, the orange RACEOPT progressive springs range from T3.2 to T4.2 to give a predictable increase in stiffness as the suspension compresses. That gradual ramp helps keep the car composed on mixed surface runs.

Balance Between Grip and Support

These springs offer an initial softer response for traction, with growing support under heavier loads to reduce excessive body motion. The result is improved mid-corner stability and better control through choppy sections.

Quick Upgrade Path for Hobbyists

They are easy to install and intended to fit most 1:8 GT shock assemblies, allowing quick testing of spring rates without major chassis changes.
