For 1:8 GT builders aiming to sharpen handling, the orange RACEOPT progressive springs offer rates from T3.2 to T4.2 to change how the chassis responds under load. The progressive profile smooths small inputs while providing extra support during aggressive cornering.
These springs help maintain tyre contact by softening initial movement and increasing resistance as compression deepens, which promotes steadier cornering and predictable transitions.
They are straightforward to fit into the majority of 1:8 GT shock units, allowing quick setup changes without major chassis work.
