The Yokomo RS-BTC Belt Tension Cams are resin components built for precise belt adjustment on RS1.0 chassis. By choosing fixed cam positions you can alter drive belt tension and influence how the front and rear differentials share load during cornering.
Correct belt tension keeps drivetrain response predictable and helps avoid belt jump or excess wear. Using the Yokomo RS-BTC cams you can hit the sweet spot where belts run smoothly without binding, which helps lap consistency when conditions change.
These cams are designed for RS1.0 models including RSR-010 and RSR-LFGT3RTR and fit without special drilling or kit changes. A few simple tools are all you need to swap the cams and start testing new tension settings.
