If you use a diamond grinding tool similar to the flywheel grinding as mentioned earlier it may work but chances are that they will shatter.

Well, people have told me before some things could not be done (using 964 cylinders on a type 4 for instance), but I am a stubborn sob....

Today I wanted to show you it IS possible to machine them and I HAVE done it!





They look fiber-ish, but are very smooth, I assure you Its just difficult to capture with a flash light.

Still not proof they will work on the car, but one thing at the time

Good for you Wally !

Strong will and determination do go along way (911 shrouds don't cool )

Let us know how those brakes work out so we can envy you even more.

Good job.

Sandeep

Nice job, the fact is anything is possible if you really want to do it!

Good job Wally. I like and support your against-the-grain thinking! Keep it up!

There you go, you've done it. High speed grinding, washing the particles off with lots of water. So you think they are safe to use???:
Do what you want, but don't be a danger to other road users. Note the attached PORSCHE technical data referring to brake wear limit.

Wally, you're an inspiration to me. I love it when people do things that others call impossible.

Keep the innovations coming!

Today I test fitted the disks and calipers on the existing M030 spindles. The 350mm disks still fitted easily in the 18" rims

It looks incredible.



It looks like the surface is different from factory. Did you grind off a surface coat? How wil that effect your brake life/performance?

Like I said though, it looks incredible.

As I understood from the company that only does ceramic machining, there is/was no surface coating. The surface is super smooth again, but like I mentioned before, it just is diffcult to capture by (flash)photogragh

There really is only one way to find out if it works

I just meant that the grains now look a lot larger than the factory surface. Good luck with your tests, just make sure your seatbelt is tight, and your insurance is paid up (God forbid anything should happen).

I think the first place where Wally is going to test them, is on the track

From what I've read, that would be a bad plan. The factory doesn't recommend these for track because the thermal conductivity is really low compared with iron, and the heat destroys them REALLY fast. Apparently most people bought these and are not saddled with 10 000 USD repair bills after a few track sessions. Is that perhaps where Wally got his?

Yes, you are totally right: they suck, don't brake well, are unsafe on the road and especially on the track and in general just a very bad idea.
This is all before I even tried it.
Whatever...
