This aluminum wide wheel hub set is designed for Kyosho Optima Mid series RC vehicles, providing a crucial upgrade for enhanced performance and durability. Crafted from precision-machined aluminum, these hubs significantly increase resistance to bending and wear compared to stock plastic components, ensuring more consistent wheel rotation and alignment under demanding conditions. The +2mm offset on each hub effectively widens the vehicle's track, improving overall stability and cornering characteristics, which is particularly beneficial for competitive racing or aggressive off-road bashing.
