I've never warped real BMW disks, every fake has died.

'Baught' strange spelling (not typo as done twice)

Being concerned about ventilated discs with different thickness sides, and
on the thinner sides looking "like they've been turned by a ham fisted blind
man" can hardly be described as "being overly fussy about the cosmetic
appearance"

Those are not cosmetic faults, they are machining and design faults, which
will affect their service life if nothing else.
Personally I don't think they were originally made for an E38 740i.
Delphi is a reputable Co. I'm sure their pattern discs would look identical
to the originals. They would know as well as anyone else with any sense,
that the two flanges should be the same thickness. IMO somebody has modified
discs designed for a different vehicle. Turning one side so the disc is the
right thickness, and runs in the correct place relative to the caliper. It's
the only logical explaination of why one side is thinner than the other.

One thing I can say for certain. I'd never put similar discs on a car of
mine, even if I were given them for nothing, and to charge £40 pounds for
them, when equally as good quality new discs can be baught for £35 is just
adding insult to injury IMO.

Personally I'd send them back, telling the supplier exactly what I thaught
of them, and demand my money back, including the return carriage cost.

One of Mike's endearing little foibles. ;-)

Perhaps it's an old english past tense spelling?

You're right it's not a typo. If I think about it I spell it right. If I
don't, I always get it wrong. I just don't seem to be able to cure myself of
the habit. I suppose it's because phonetically an 'a' seems more appropriate
than an 'o'. That's my excuse anyway.
At least I don't refer to a cars breaks. :-)

Something like this has come up on another group with an E39 540. Seems
there are two types early and late. Fit the late ones to an early car and
the disc rubs on the caliper...

Thank you Dave, but it's not really my fault you know. :-)
Problem is that baught looks more right to me than bought, so I don't notice
it in the way I normally notice spelling mistakes.
If I were picked up on it more frequently maybe I could get out of the
habit.
Come to think about it I make the same mistake with brought, but it's not a
word I use as much.

Or maybe it's a long forgotten alternative spelling which might allow me to
continue using it. Must check. :-)

LOL - you're right - 'breaks' is positively cringe bringing!

You can't try that one unless you're 96 or older! (and then I'd hope you
weren't messing with brake discs - or for that matter even driving!).
If you're going for the phonetics, surely it should be bawt or bort?
But then we'd be getting into SMS language and that's destroying our
illogical old English as each day p***es. Just you see the state of the
Oxford dictionary in 10 years.

Actually - on the OP subject of discs, I note many responses are going
on about the fact the inside and outside sections of the disc are not
equal thickness. As far as I know - this is not necessarily wrong. I
haven't played much on BMW's yet as up to recently I was a VW man - but
some Gold models have this and when this is the case, the inner brake
pad is smaller implying that the inner calliper applies less pressure
than the outer - meaning less wear and therefore thinner disc section.
Are your brake pads the same size? If not and the smaller one works on
the thinner section - that seems OK to me.
Best
David

To me I see "au" as either "oh" as in french, or "ow" as in german.

Naught for example up north is pronounced "nowt" and you'll find that
southern England words have more in leeping with French pronounciation
while northern words are more in keeping with German and Scandinavian.


To go back slightly OT, the pads are the same size.
