Use 2010 for all race cars of our team - Subaru Impreza, Nissan Silvia.
Nuts are experiencing a wide variety of loads - different mechanics, different tools, different haste, because during the races regularly something goes wrong! Unscrew and tighten their manual, pneumatic, electric tools, removing the wheels hundreds of times a year - and still I use the same nuts that put it on the car to try the advantages of the rotating sleeve on the cone nut.
The higher the quality and reliability of these confirmed nut case.
