Pro-Sim Sequential Shifter has been exclusively developed with world renowned gearbox manufacture Quaife Engineering. This shifter is the exact same mechanism used on a current production Quaife gearbox so the feeling is exactly the same as driving a real car. Being from a real car also means it is extremely robust and you can be very aggressive without the fear of breaking anything. This shifter is also a work of art and with the Perspex cover you are able to see the complete mechanism working on every gear change which is something very special.
