This is the shape for the e92 m3 N caliper (both 380 and 365). I just swapped in my set of me20 today. Thickness including backing plate is 18mm. These pads are very very large.
IMO a larger friction area should distribute more effectively, leading to lower wear rate. Stopping power is not affected.

those numbers are correct (and that's a big if
), it would mean the GT caliper has a pad area 35% greater. I know pad area isn't everything, but that's hard to overlook (though it basically just translates into burning through pads & rotors faster).
Can anyone with actual knowledge
comment on this?
AP lists the pad area of their CP3894D54 pad as 77.44 cm^2 (source: http://22.214.171.124/ProductDetail.aspx?ProductID=3031
). I can't find a comparable spec for Brembo's 07.9551.13 pad, nor actual confirmation from Brembo that this is the correct pad for the Monobloc 6-piston GT Kit# 1NX.XXXX (and I can only find a hint, in their application sheet, that this is the correct caliper for the E92).
[AP definitely wins on the amount of specs they provide. Does Brembo really have no datasheets or mechanical drawings on their website?]
