New from Exotek Racing come several aluminium option parts for the Xray XB4 buggy in the form of rear hubs, servo and wing mounts. Starting with the rear hubs, the parts are machined from 7075 aluminium and sport vertical camber ball stud mounting positions for easy roll centre adjustments using different thickness shims. Included with the parts that come in orange or black colour are 2mm spacers to match the stock geometry of the kit’s plastic hubs. Next up are aluminium servo mounts, again machined from 7075 aluminium. The parts offer higher rigidity and sport a lightweight design and come in orange or black colour. Last but not least are the aluminium wing mounts. They are of a heavy duty design and add a huge amount of durability while being light of weight at the same time. Just like the other XB4 parts they are available in orange or glossy black colour.
