The Yokomo B10-S3SA short shock spring cup lets builders make accurate preload and spring position changes on BD9/10 chassis. It is made to give predictable response so your car reacts the same lap after lap.
Custom fitted for BD9/10 cars, the Yokomo B10-S3SA reduces spring wobble and helps the damper work more consistently. The result is cleaner weight transfer and steadier corner exits for drivers aiming for lap time consistency.
This component is compatible with MDR-020, SDR-020, and MDR-020BL chassis options, making it useful across different builds. The installation process is quick and straightforward for club racers and weekend tuners.
