If you are tuning an XRAY 309822 - T4f'21, this 30g front chassis weight is a practical upgrade. Precision-machined from brass, it secures to the factory front holes and helps shift weight bias forward for improved steering feel and more consistent exits.
The unit aligns with the T4f'21 pre-drilled locations for hassle-free fitting, so setup time is reduced. A visible laser mark of the gram value makes it easy to identify during quick pit adjustments.
Brass combines a compact footprint with high density, giving effective mass without bulk. Used to lower the centre of gravity, it helps the car turn more predictably and maintain stability through fast sections.
