Big rotors too.
The rotors on M50d are 385 mm at front vs 395 mm on X5 M.

Had a look at the X5 M rotors & brakes yesterday at the local BMW dealer, the calipers on the M50d actually hold a larger brake pad. The caliper on the M50d is only a twin-piston so it looks like the pad itself is bigger as one would assume the performance of the M50d caliper would not be of the same caliber as the X5 M system, they are a different design.

ASIF they are going to do several rotor sizes. My 40D (which is sold as a sport in Australia) is 365mm rotor on front. The M will have the bigger size, the M50D will have the same rotor.....

The M50d has 385mm front rotors (have measured mine and bought ceramic pads for it), the X5 40d came with 365mm, the X6 40d comes with 365mm in Australia

In Europe the X5 40d & X6 40d has 365mm rotors due to there Autobaun high speeds, also for Europe the X5 & X6 50i comes with 385mm rotors.

The 2008 X5 35d models came with 365mm but the 2009 X5 model was dropped back to 348mm for Australia

The 2007 X5 30d, the first of the E70 series came with 348mm for Australia.

US gets 348mm & 365mm on diesels & 365mm on the 50i models, but that can change for one year to the next.

Its seems to be a bit of a mixed bag, the 30i & the 30d have 348mm rotors and the 40d & 50i have 365mm. As you go up the power scale the rotors get bigger, as mine has 385mm with twin piston calipers wheras the others only have single pot. X5M has 395mm.

Looking at my rims I don't think you could fit 19" rims on, it would be close but I think heat due to lack of ventualtion would be problem, hence 20" wheels are standard.
