Selecting Neutral in Gransport to save clutch when stopped in traffic?

Agree with you about the clutch drag. But the rotation of the rear wheels happens when the clutch is engaged and the car is in neutral because friction within the box it turning the main shaft.

Yes, fair point!

Would this be a good way to set up the PIS, have the rear wheel off the ground and set the point so the wheels don't spin?

It is, but there's no clutch wear because the plates are engaged. The wheels turn due to drag in the box. Where you've got the clutch disengaged, you're in gear and then the wheels turn, the plates are dragging and therefore wearing.

Either way, whether there is drag when stationary or not I’d guess the wear is nothing compared with that from pulling away.

We do seem to be overcomplicating it. In gear. Foot on brake, plates are open and the wear is on the release forks (or bearing, I forget). Assuming correct adjustment. In neutral the plates are engaged, there's zero wear on them.

Kind of. When I was setting my PIS I wanted a quick gear change, so the method was, reduce the PIS, go for a drive, check there was no creep and that it would select reverse.
If there was creep, back it off a bit. In my estimation, if it is to the point of creep and then backed off, there might still be some (admittedly very minor) contact.

Yep. Voicey did mine my measuring the output RPM in gear, foot on brake. In theory 0 RPM. Then you got for a drive!

Used to do this on my first 4200, but not on the latter two. My wear is c1 or 2% per 1k miles... so I can't see the point of changing to N as this would just wear out other components more rapidly.
So, at your current usage, you are looking at 1% clutch wear every two years.
There are glaciers melting quicker than your clutch is wearing!

I've done 60 miles this year... so far... ir would have been 170, but the extra ones were a transporter trip to SI for some pipes... its still there on holidays waiting for the return run on the back of something..

As its high miles I am trying to redress this but carrying it everywhere.

Exactly, unless it’s dragging.

It opens to the PIS, where there can still be some drag, is my understanding.

I have seen CC gearbox cars on ramps at idle with the rear wheels turning very slowly. This is why I drop into neutral.

But everyone pays their money and makes their choice.
I believe it opens it fully, not to the PIS. The PIS point is used to start engaging the clutch exactly in the same way that you'd bring the clutch up to the biting point to move away on a manual. If it sat at the PIS, you'd kill the clutch really quickly, as in tens of stops.

If the positions are off, it is entirely possible that there will be some drag and the wheels will spin.

It's obviously slightly better to go into neutral from a wear perspective but not necessary.

If I'm comng up to stationary traffic, I'll often put the car into neutral and coast / use the breakes to come to a stop.

I am only saying what I was told when I was told when I was having mine set up by Ed who is now at AV engineering. It’s my reason for doing what I do, I’ll carry on until I know for sure it is another way.

Interesting and reasonable. But it's highly likely that your foot will come off the brake as well....

Why would I care about hitting the car in front? Major insurance ballache is coming anyway so with modern insurance policies and owning a Maserati it is likely to be awful. And in 40+ years of driving I have been rear ended once so why worry about a vvv rare event?

OMG!
Where's the fun in that? Might as well have an auto! :frusty5:

Bang it down the cogs and listen to the V8 symphony!! :thumb3::1408:

V8 symphony from 30 or less? really?

Creeping along in trafffic when the clutch is slipping is one of the things that wears the clutch out.

My two cents worth… most of the time I don’t do this on my GS, and I remember asking Miles at Emblem about whether I should, and his view was it’s not necessary

Ah........but you didn't say creeping along in traffic, you said coasting up to stationary traffic, completely different. ;)


Seriously though, one of the amazing things about these cars, is that they sound just as gorgeous doing 15-20 mph through town as they do singing on the open road! (unless of course you coast in neutral) :)

Totally agree I used all my cars daily when living in WsM in Somerset and going to work at 07.30 was a treat for me and many others especially in the 4200 and 360 Good Times indeed :)
