I have decided to take the bold step of fabricating my own gear shift mechanism. The reason being that I prefer the cable shift to rod operation but dislike the driver's seat being offset from the centre of the steering wheel.

So my plan is to take the standard 996/997 gear shift mechanism and produce a narrower version. This will allow me to have the seat more aligned with the centre of the steering wheel.

I may also raise the mechanism and generally play with the positioning to suit my seating position.

My question really is regarding IVA. Will I need to fabricate a custom console to surround the mechanism or can I leave it bare and exposed?

Also, does anyone have a 996/997 mechanism they no longer require?

The mechanism can be open.

Interior sharp edges apply above and below a line measured 150mm up from where your bum is in the seat.
Above that line edges contactable with a 165mm sphere (in a forwards direction) must have a radius of 2.5mm min. Below that line edges contactable with a 100mm sphere (in a forwards direction) must be blunted. I've yet to find a definition of blunted but suffice to say I have seen a requirement for a 0.5mm radius specified so blunted has to be less than that.

Your gear mechanism may be in part above or below that line however elsewhere there is a specific requirement for gear levers being any edge contactable with a 165mm sphere (in a forwards direction) must have a radius of 3.2mm. Quite why this is beats me.

Thanks steve for your response on this.

Can anyone using the factory supplied centre console/996 mechanism tell me what their steering to seat centre offset is?

By fabricating my own mechanism I hope to reduce the unit width by at least 1.5 inches.

If I can get an idea of the current offset that would allow me to determine the gains.
