Looking at replacing some discs on a 1994 M944. Any major advantage of one over the other besides weight savings on the alloy carrier? I'm guessing the actual rotor part is the same.
The steel carrier would have less wear on the button recesses I guess. The Snowflakes cost less than the Pizzas at Yoyodyne.
BTW the EBC discs look promising at CCW.
They all work fine with the right pads IMO.
I have full floating with alu carrier - only now after 50-60Kkm are they showing wear to be concerned about.
The gyro forces weight is less to worry about than unsprung weight, I'd think...
Which means, as it often does, that you choose what you like to look at 8)
Snowflakes have a thicker rotor, 5mm vs 4mm.
They're a good bit lighter, rough calculation is ~300g, as I've not had a brand-new 'pizza' rotor to weigh.
I just removed a 'snowflake' from my M750, 24k miles of mostly easy freeway commuting and it was worn below spec.

The OEM 4mm boat anchors last me about 38K miles, blades worn below limits, carriers and buttons still great. I replaced them with Alth semi floating (thogh less semi than Brembo) 5mm aluminum carrier. Blades held up fine, no wear on one carrier, at least .5mm on the other one at the buttons after maybe 12K. I now have 17K on semi floating 5mm snowflakes. All is good. My guess is poor anodizing on the Alth that wore prematurely. I would assume carrier wear would be more of a problem with full floaters.
Thanks fellas. [thumbsup]
Make sure whatever you buy has "MIN THICK xxMM" stamped on the carriers or your insurance robbers (and/or [leo]) can spoil your day for ADR compliance failure.
EBC disc I was looking at for my DR had no "MIN THICK" identifier so I had to passed on it.
Thanks.
He went for the snowflakes, so 3.6mm stamped on them?
which snowflakes are 3.6mm min? sounds like a steel carrier to me.
That was meant to be a question actually. My pizza rotors with steel carriers have 3.6 on them. What do the alloy carrier snowflakes have?

4.5MM
Thanks Dan. [thumbsup]
Ok, with the Pizzas being 4mm and snowflakes being 5mm, the pattern here is that there is about half a mm wear available on these stainless rotors.
Thanks guys.
