The RACEOPT 1:8 GT Progressive Dynamic Spring - High Response was developed for club racers and weekend tarmac sessions who need a responsive suspension tune. The progressive T3.2~3.4 rate gives a forgiving initial travel while stiffening up under harder loads.
These springs boost tyre contact when it matters, smoothing out transitions and providing more consistent handling during faster laps. The progressive layout helps avoid sudden weight transfer that can unsettle the car.
Compatible with most 1:8 GT shock towers and spring retainers, these coils are quick to fit and allow fast setup changes trackside. They are a practical upgrade for a range of GT models.
