CNC-machined hardcoated duraluminum rear wheel axles with hex hubs. Ultra-true, direct, wobble-free wheel mounting ensures slop-free wheel rotation. Wheel axles have been strategically lightened to reduce rotating mass without compromising strength. The wheel axles feature a +1mm offset which means that they are 1mm longer than standard wheel axles. Using the offset wheel axles will increase the overall track width by 2mm that will make the car more stable and easier to drive.
