For me I identified the models that shared the correct calipers and carriers and searched 'Breaking' and 'dismantling' of those models on the interweb. Searched a lot under 'E46' rather than 330
The carriers do have markings on them but you would not be able to see what the markings were fitted on a scrap car.

I made the judgement that if I found a car being dismantled that had those parts fitted as standard then........... 'bingo'

Just saw these

Thanks for the replies mate. I've done the same, a lot of the cars that come up, once I call up requesting the part they've already sold. It's apparently a very popular mod with the old 3 Series too, the e36. The odd occasion they do have them they're asking in excess of £100. It's been mentioned a few times that they can be had for around £60. So looking at that sort of figure £60-80 ish.

Found a reasonable one! Link here. I'm going to see if he'll let it go for a bit cheaper tho!

Why wouldn't you just buy them and before posting? If the calipers are trashed then you can use them as cores to trade in. If not then you have a bargain.
Someone is likely to see the post and just buy them

Just bagged a set for £70 from a breaker I contacted over the weekend so all good!
Also, I know some people are like that. However I'd like to think that since this is a forum, of fellow enthusiasts, I'm among friends.

Brilliant that you have got a set
In terms of 'trust' I agree and in general you are right, however at any time there are up to 500 guests on the site. There are 200 now as I post this .., so it's a wide audience

Yes, finally!
Noted about the second comment! I'll be more weary about things in future

Someone at the Duxford meet (apologies - cannot remember your name Mr '58 plate Montego Blue owner from Bucks who's going to LM with Airtrack this year) was sporting E46 M3 front discs on his 3L coupe - identified with the help of some Rain Man action from Stu Boy.

I had a look at the specs...
So ok... stock pads won't sweep the whole disc, and fresh pads and discs will be a bit of a squeeze, but the hub fits and the diameter is perfect.

Doesn't this make new or part-worn E46 M3 discs a decent upgrade option for 3.0si owners? They are nice, 2-piece drilled rotors and supply should be plentiful (in fact, I think a stock surplus is how the aforementioned gentleman secured these discs at a bargain price).

Interesting comment.

I think I did look into this but outlay seems to be quite a lot more than the 330, this is for parts whether new or second hand, and not sufficient gain. Also in terms of maintenance, just costs more because of the M name tag. Also I think the actual disc is the same (325mm) its just the thickness thats slightly more on the M. Obviously braking power of the M brakes themselves might be slightly more but not THAT much. Also some chatter on the 3 series forum about issues with the calipers being a direct fitment.

If it was a M3 CSL (which is 340mm or something) then this would probably be more "worth" it in terms of performance gains, provided everything fits. Wasn't too sure which is why I never pursed it myself. 330 is tried and tested...

The whole purpose of this thread is for a cheap, easy direct swap and bolt on conversion.
Once you start to mix and match, add pads that don't fit, ///M parts it'sa different topic altogether.

Fair point. I did think that "bolt on" 2 piece floating rotors and >5kg less unsprung mass for ~£200 was pretty good value, but yes - not cheap compared to the other options in this thread.

Point is probably moot now. Doing a little more digging, I think they were actually these OE option for the 3-series. And those definitely aren't cheap!
