The RACEOPT Progressive Dynamic Spring set, finished in yellow and black, provides a stepped-up approach to suspension tuning. With T2.5 to T2.6 ratings, these springs supply a progressive increase in resistance that helps stabilise the chassis during aggressive inputs.
These springs are engineered to change stiffness as the suspension compresses, helping keep tyres planted over both small chatter and larger impacts. That layered response improves predictability when changing lines or accelerating out of corners.
Fitting these springs is a simple process and they are compatible with many standard shock assemblies used in common RC cars. They are ideal for modders who want improved suspension behaviour without replacing shock bodies.
