This JR Side Mass Damper Set gives Mini 4WD enthusiasts a way to fine tune chassis behaviour by adding mass to the sides of AR or Super XX models. The design aims to smooth out transitions and reduce abrupt weight shifts during turns.
The kit includes custom side plates that bolt to AR chassis side stays and accept the supplied mass dampers. You get both bowl-shaped and cylindrical dampers so you can try different setups to suit various circuits.
Mix weight configurations to adjust handling under braking, mid-corner, and on exit. Gun metal ball caps and mounting screws are provided to keep the setup secure under race stresses.
For club racing and practice sessions the dampers help maintain tyre contact and aid smoother line holding. Their compatibility across AR and Super XX chassis makes them a versatile tuning option.
