Team Bomber AK12 castor block support
From Team Bomber for their AK12 chassis are these carbon castor block supports. The new part improves the twist stiffness of the block body by just installing it on the genuine caster block mount, which improves the accuracy and response of the handling on high traction surfaces. A very effective item for the setting of handling characteristics for various track conditions and layouts.
