In the world of social media this discussion often comes up with internet experts trying to tell us our shifters are not a true sequential. Well the hard fact is that our shifters are as sequential as they can possibly be, the definition of sequential is for it to be in order. A sequential gearbox is not necessarily a dog box and a dog box is not necessarily sequential, the internal engagement method is unrelated to the shift pattern. Our sequential shifters work great with dog or synchro gears.

Of the two methods synchro engagement is by far the most refined and greatest technical achievement but the dog engagement definitely has is place in some race cars.
