The Revolution Design Racing Products Battery Positioner Brass 45g Setis designed to replace the standard RB6 plastic battery positioners with heavier parts in order to adjust the overall weight and weight distribution of the buggy. Included in the set are two brass battery cups that can be used in the front and the rear of the battery and also separately in combination with the stock plastic or the RDRP0211 Battery Positioner Aluminium Set to achieve an ever wider range of setup options. The brass mounts are precisely machined, they come laser-etched for easy identification and include black anodised aluminium posts for the battery mounting plates.
