Serious RC tuners who want crisper front-end control will value the XRAY 309825 brass weights for the X4F. These 50g units sit in the centre of the front suspension where the bumper used to be, shifting mass to improve weight transfer and boost rotation during acceleration and braking.
Manufactured from dense brass and CNC-machined to tight tolerances, these weights deliver consistent mass and fitment. The black coating helps resist wear and the laser engraving provides clear part ID and a tidy finish.
