Nope, not in the US. My front rotors are just as small as every other 328 I see lol.

I tried these MPB on my buddy's 320i.... and i find them a bit too soft.
When i had my AP Racing 7040.. they were firm and bite is very good.

I don't get it y the MPB will make those pedal soft.

But according to the ETK it has the same part number as standard EU front discs.

Would love for that to be true, but I am 99% sure that is an error.

So u mean the ETK is wrong, when it specifically lists option 337 as having that particular part number? It's not only the discs but the brackets as well.

All publications, such as REALOEM and exploded views with part numbers I have seen of US cars, all 328's have the same hardware, only the pads are MSport specific.

Kind of sort of on/off topic but this is my thread so who cares...... My MPB kit should arrive tomorrow!

Well, 330mm rounds out to about 13", 300mm comes out to 11.8"

I will measure mine, someone else with US non MSport will need to measure theirs and we can put the debate to rest.

Didn't feel like starting a new thread about this and you guys seem to know enough about brakes.... Just got my MPerf brakes and there is a ding on the edge of one of my rear rotors. Do you think this is cosmetic only or will it effect anything?

The ding is only 3-4mm or so. Very small but you can definitely feel it when you run your finger over it. Thoughts?

Someone dropped the disc on the floor? I wouldn't worry abt it unless it's cracked but ask for an exchange if u can.

My shipment came in two boxes - one weighed 100lbs and the other with the rear discs was 40lbs. Theses heavy boxes looked like they fell off the UPS truck and rolled for a mile before they left them at my door step.

Even the brake pads were completely out of their individual boxes but it doesn't seem like there is damage done to those.

Sucks b/c I really wanted to install these today! Anytime I get a UPS tracking number when its something of value, I just pucker.

UPS needs to replace that...it's more than cosmetic, as your rotors wear, if they scrub evenly (like I would imagine), you would risk uneven wear and/or vibrations...
