For modelers looking to refine suspension response, the RACEOPT Progressive Dynamic Spring set is a practical option. The pack contains four progressive springs spanning T2.5 to T2.8, giving a useful range to tweak ride height and midstroke support.
These springs are ideal for drivers who want predictable handling across different surfaces. They help reduce harsh bottoming while keeping the chassis stable during hard cornering or uneven runs.
The springs are compatible with many common shock designs and can be installed with routine RC tools. Quick to swap, they are handy for testing different setups between practice sessions.
