This set adds side-mounted mass dampers to help settle a Mini 4WD chassis after bumps, jumps and lane changes, improving straight-line stability. It includes two FRP side plates plus four mass dampers — a mix of bowl-shaped (3.4g each) and cylinder-shaped (4.2g each) weights — so builders can experiment with damper mass and placement. It fits FM-A, Super XX, AR and MA Chassis cars, though some chassis or bodies may need modification to clear the side-mounted dampers.
