The Kyosho OTW130 spring adjusters are a compact way to refine your RC's suspension on 13mm setups. These black adjusters come two per pack and let you alter spring preload and ride height without major disassembly.
They suit the TURBO OPTIMA and other models that use 13mm collars, allowing small changes to handling and corner balance to be made quickly at the bench or track.
Install the adjusters with the model on a level surface, make small incremental changes, and test between tweaks to find the best balance for grip and stability.
