Pro-Sim Sequential Shifter
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.

Description
The new design features a gear lever that is easier to adjust and to many more positions. The new design of shifter is quieter than its version 1 and also more robust, added also is an adjustable plunger now so that you can chose the exact strength of gear change required. The main advancement on this version is the optional active shifting that uses a hydraulic system and software to only allow gear shifts when the gear is unloaded exactly like on a real car.
This shifter can be directly bolted underneath using 4 M6 bolts or alternatively you can bolt our attachment plate to the shifter and bolt through the 4 holes from the top into your setup
Material
One big differentiator of our gear shifters to the current market is the material. In a market where plastic products have dominated, people often think ‘metal’ is considered the hardest or toughest material that could be used. For us just any old metal is not enough. We use the highest quality steel 835M19 often found in aerospace applications and go one step further to apply heat treatment to case harden the material. Once the material has been hardened only the most specialised carbide/diamond tools can be used to perforate it. We do this for ultimate durability on all the critical components, creating a shifter designed to last a lifetime.

The main problem with all shifters on the market at the moment is that you cannot simulate missed gears nor have any interaction with the software. For this to be accurate it also needs to simulate the different type of gearboxes for dog engagement and also synchromesh:
Synchromesh
A synchromesh gearbox is what you would commonly find in your road car. This type of gear is engaged using cones to match the speed of the gears and then held in place with multiple ‘teeth’. With this type of gearbox there is virtually no play when in gear but there is a lot of surface area with load on holding the gear in place. Because of the load on the teeth and the fact there is not much space the gear needs to be doing almost exactly the same speeds to be able to engage and this is what the cones do but they cannot overcome the engine brake without doing damage to the gearbox and so the clutch is needed for all changes.
Dog engagement
A dog engagement box is what you will commonly find in race cars and on most sequential gearboxes. This type of gear usually has 3 to 6 ‘dogs’ on each gear and there is a lot of free space for them to engage this means there is normally quite a lot of play when in gear and why you often see race cars juddering forward and backwards when going down the pitlane. When you are driving fast this is not an issue as you are pushing on one side of the dog for acceleration or braking rather than hovering in the middle, this is also why they are not suitable for daily use on the road.
When shifting gears because of the space between the gears normally there can be up to a 900rpm difference in gear speeds and the gear will still go in, because of this you do not need the clutch. To make a gear change you need to reduce the load on the dogs so that it can released, this is normally done by just lifting the throttle on the up change. To change down a gear there is already a reduction in load that is sufficient you just need to blip the throttle so that you do not lock the rear wheels or cause unnecessary wear on the gearbox.
