My Ride: Modded 2010 Carbon Black M5 SMG and Modded 2008 Dinan 550i Sport
Personally I don't think you need them nor would I recommend them. They will add a ton of weight to your car at the corners. That is why I never did on my Dinan 550i. When I look at them now on my M5 it reminds me why I didn't. It is overkill and not a real advantage. In fact, it could be a disadvantage with the weight.

My Ride: 2008 550i sport package
Good point. Unless you're tracking your car and need to do repeated high speed stops there is no advantage in stopping power. Read the 60-0 and 80-0 braking distances for an M5 and other 5 series. You'll see there is basically no difference. You can get the online results from Car and Driver/Road and Track magazines.

My Ride: Plucked bmw.....

And a caliper on 550i weighs 3.881kg / 8.556 lb, and on M5 4.296kg / 9.471 lb.
So, how and where then it could occurs overweight, when brakes on M5 are lighter than on 550i?

tech its 29lbs front and 21lb rear for the M5. Plus pads and calipers. It might add like 25 to 80 pounds extra. but its good weight. Like a roll cage or chassis bracing. Coil overs add weight,
You guys have a V8. I had them on my gutless 2.5L 6cyl and it made a huge difference. I offset most of the weight by reducing other aspects of the car like sway bars and spare tire junk and lighter wheels. Why not have the best factory brakes when your being silly with your 4,000lb vehicle. I had 4 instances with surrounding drivers being stupid to a point where the cars stopping power came into play and they saved me and them.
My friend has the M5 with 8 piston BBK and he sold me and help install the brakes and laughed hysterically when he took my car for a drive and saw what the brakes do on a car that weighs. 600lbs less.

I believe it takes you a second to say " a thousand one"..if said roughly 4 times its 4 seconds. not scientific but it works

the brakes are no good for the track cause eventually there is brake fade cause the pads arent made for the track. you would need "ring taxi" pads for that, then they wont be any good on the street. In my test from 110 to 55 it was 4 one thousands i counted. These monsters rotors were warm to the touch just on a 3 mile stop and go city trip. yes it will eat mpg but for day in day out daily driving theyre really hard to beat for the price
Good luck with the project!
