There's a big difference between 120MPH and 150MPH. In fact, a huge difference. At the BMW Performance Center, they demo'd how much further it takes to stop a car with just a slight increase. I think the X3 they used stopped in 20 feet from 20MPH and then 40 feet from 30MPH. So if the SLR really can stop in 400 feet from 120MPH and assuming the M5 can do about the same, I'd guess it would take about 900 or 1,000 feet to stop from 150MPH. To be honest though, at that speed, I really don't see how that's possible. The fastest I took my car was up to 140MPH and it felt like if I had to stop I would have made it to Mexico before I got to 0MPH.
