The 3RACING M4WD-07/LB bowl weight at 3.5g is a precision mass damper intended to stabilise transient responses in Mini 4WD cars. It is compact and designed to integrate into typical Tamiya mounting points while adding controlled inertia to reduce unwanted oscillation.
Functioning as a tuned mass damper, the bowl profile helps localise mass and damping effects. The part suits a range of Tamiya Mini 4WD chassis and can be positioned to alter pitch and roll tendencies depending on race setup goals.
For race tuning, use incremental adjustments to mounting position to dial in balance between stability and agility. The 3.5g mass provides subtle damping that can improve lap consistency on technical sections without compromising acceleration response.
