The Kyosho OTW130 spring adjusters offer an easy way to tweak suspension on 13mm-equipped models. Supplied as a black pair, they let you alter spring preload and ride height without removing shocks from the car.
These adjusters are a good match for the TURBO OPTIMA and any RC model using compatible 13mm spring collars, helping you tailor handling for different track surfaces.
Fit and test on a level bench, tighten incrementally and re-check handling after each small change to avoid over-adjusting the setup.
