I have the m5 rotors and calipers front and back. The front has no issues with installing. The rear rotors doesn't fit the back completely without removing the metal bracket. YOu'll find out when you install it. As far as with rims, i have 20" rims so the clearance is fine, not sure about 18" rims fitting on the m5 rotors.
also regarding fitment of 18" rims to an M5 :

I hope they'll fit without problems.

Don't forget to report if "they'll fit without problems"

ill second this, brakes are drilled/dimpled/slotted/cut for outgassing and heat dissipation not pad dust.
Personally id look for slotted and dimpled, they keep the structural integrity (as mentioned) and the dimples act like cross drilling in terms of outgassing if not heat dissipation (drilled cant be matched for that - just dont get them TOO hot, or wet&hot, or any serious debris on them)
AlexFW - you would be surprised how much difference the same calliper with better rotors and properly bedded pads(which you should do anyway) can make compared to stock. Add even slightly better callipers and id wager your jaw will drop at the difference.

Don't worry ...you won't need them!!
Also they are 50gr. heavier than the 545 ones, they could affect your 0-100 performance by 0.002 sec

Don't worry, I can load 200 Kg continuing to be under 6s

Soe, I and nicke60gre were intending M5 front+545/550 rear versus M5 front+rear, discussing especially about the diffence between rear calipers.
For sure the difference has to be very small .
(If you want drilled rotors for 545/550 you can find easily on the web for a few dollars)

There was only 1 set of oem 17s that fit the E39 M5, style 66. none of the other oem 17s available for the E39 would fit. I know because I had to give up my beautiful style 19s when I upgraded my brakes to M5 ones on my first E39.
do a test fit before you commit, or be ready to buy 19s or 20s at a moment's notice. THere's nothing worse than trying to put the wheel back on the car when you're done and hearing that clunk! when they don't fit. BTDT.
