Im not surprised you beat him. I have a 2010 GT-R. Makes sense to me?
M3 is 420 hp and GT-R is 485hp. You have to be making at least 520hp and the car weighs less.
I also agree with 997 gt3. Unless you guys have driven a GT-R, or ventured to the forums, you wouldnt know that the GT-R pretty much starts to fall on its face after 100mph. Ill even admit that it doesnt pull as strongly. The AWD really helps down low. There are a lot of cars that would surprisingly keep up or pull on a GT-R in a 80+ race. Now, the 2012 is a different story with 50 hp or so more.
Current Stable: Some Audi with a V10, Couple of BMW's, one F Car, and one P car. One lonely GT-R with all the Euros.
