NUTS

[David W.]

Changed C4s onto winters today, the rear nuts (this car has factory spacers) on my 55 reg had deteriorated so badly that several were as photo and 1 had the have an 18mm socket hammered on to undo it. They seem much softer material than the bolts on the front. Luckily I had 2 spares which anti-thefts had replaced. Be aware of this if changing at home. I will be getting a new set next week and replacing all.

Porsche nuts are pretty much a service item. I have replaced quite a few on mine.

The upside is that they are ultra light!

Worrying when you have to hammer on a smaller socket to get a nut off! Not sure what plan c was but luckily plan b worked.

At least they don't rust like the 996 997 versions. :-)

Use this on the threads and you'll be fine in future.

Its not the threads. Its the fact that the alloy becomes brittle and gets hammered with air guns and then breaks up.

But if the threads are lubricated so not tight or seized, surely the bolt head should be able to take being undone?

Mmmm. I see what you are saying and maybe it could help extend their life but I think that the core issue is that alloy is brittle and is easily broken up by air guns.

+1 and the act that garage doesn't push socket fully on nut.

Just don't let garages and tyre fitters use windy guns on your cars.
Buy a soft socket and ask them to use a ratchet, followed by a torque wrench.

I recently bought some titanium ones as a Christmas present to myself. I am not sure if this will prevent this sort of issue but the supplier does say not to use mechanical means to remove and replace them.
