There have been a few threads on the GT3/RS forum recently discussing options for torquing and loosening the centerlock nuts on our cars.

The factory has a very slick and simple solution that uses a torque multiplier and a reaction arm to smoothly bring the nut to the desired torque, without needing a helper.

This type of solution can be seen here at 9:33:


and here at 27:32:


I'm working on a similar battery powered solution that you can use at home, in a shop, or at the track. It would allow you to take the wheel off the car, and re-torque it, without needing a longer ratchet or a helper to press the brakes or hold the steering wheel straight.

Would there be a market for this sort of solution if the price point was in the $6.5 - $7k range?

Not for $6-7K. Maybe a shop would be interested. BTW, there's already something like this on the market for shops and it costs thousands of dollars as well. There are a few threads about it on here somewhere.

Thanks for the feedback. If there is currently a full solution available commercially I'd love to see it. I haven't seen a complete solution on any of the other threads yet.

I don''t get it, really. I good quality torque multiplier makes this a non issue.

Agree.
I just took one of my wheels of a couple of weeks ago (see other thread regarding clicking noise)

It was very easy with a good breaker bar. I was dreading it. But now i have done it, i actually prefer the procedure to a 5 bolt design to be honest.

Maybe at $500, it’s just not that hard to do with current tools.

With apologies the OP who is asking about their own possible solution (and I'm happy to move this info off-thread if you PM me) I spent some time looking into this ... went down a rabbit hole chasing the Hazet Porsche Tool 9450 for the CGT. It's NLA and might not be ideal.

However, I found that Hazet has a newer torque multiplier, in aluminum body, model 6800ALU-700 that has the capacity for our CL wheels.

https://www.hazet.de/en/products/tor...en_6800ALU-700

Here is a link to Amazon, just for the picture. I've found pricing as low as Euro 780 (sans shipping), so e.g. this Amazon listing is asking for a premium over tool sites.



The challenge is whether, once the CL socket is attached and the distance from the wheel increases, will the supplied reaction arm extend far enough to interfere and lock into the spokes of the RS wheels, or other wheels?

I've not found any other available reaction arm, such as the ones that extend to the ground, that are listed as fitting the splines on the Hazet.

Some measures for the arm are here in mm http://www.parla-tech.com/hazet-alum...700-2800nm.php

I think it's only about 11mm of depth, although the picture appears to be more ... if anyone is better than me at addition ( and visualization!) and can calculate the actual distances, we might have an option with this Hazet tool. It might also be that we purchase separately the longer reaction arm from a higher-capacity Hazet model, like a -1400 that extends further, and use that with the -700 body.

I was at my local dealer last week and they showed me the Hazet tool for the CGT. They said it does not fit the current 991 GT cars.

I'd be looking to make something similar but better, with battery powered electric drive. The shop foreman at my dealership said they would be interested in purchasing one once its available - and that they would like to have a tool that turned wheel removal into a one man job.

Apparently they paid a large amount for the factory CGT tool which is now just sitting a drawing collecting dust except for the once a year when the one car they service comes in.

Maybe if I had a Porsche specific shop but not as an individual.
