The AeroRotor vanes are designed using CFD for flow optimization and flow up to 30% more than most directional vane racing rotors on the market. The AeroRotors are made of Stoptechs proprietary alloy of gray iron with molybdenum that is crack and warp resistant with a consistent coefficient of friction.
The rotors are attached to the hats with aircraft quality drive pins and heat-resistant Inconel washers. The hats have directional stand offs that circulate air between the hat and the rotor improving cooling and reducing heat transfer to the hat and hub.
A cool feature is that the uprights, and hubs are the same part in all 4 corners. The rear upper control arms are the same in the right to left sides. However, the lower arms are different. This feature minimizes the number of spares a racer has to have in inventory and simplifies repairs in case of an accident.
