The RACEOPT Progressive Dynamic Spring set is aimed at modelers seeking more predictable suspension behaviour. The four springs cover a progressive range from T2.5 up to T2.8, enabling fine adjustments to roll stiffness and impact absorption.
These springs help drivers achieve stable handling whether pushing for lap consistency or managing bumpy sections. The progressive rate delivers a softer initial response with firmer support under heavier loads.
Compatibility spans a broad selection of shock units. Fitting is simple and uses standard RC workshop tools, so you can test different rates without lengthy downtime.
