LOL Data analysis? How about real life numbers from real people on the dragstrip. These are all stock GT-R also not modified. Modified numbers are on the link below.
1. Either your friend can't drive.
2. Something wrong with that GT-R
3. 2008 vs 2012-2013 obviously is a huge difference that you just don't want to acknowledge. Look at the bottom of the list and you will see 2006 M6 being beaten like no tomorrow so is that the same as the GT-R beating your M6? Beating a 2008 GT-R saying it is the same as a 2012 just because they both are GT-R are retarded. It is like me saying I beat a E46 M3 is the same as me beating an E90 M3.
4.
Your M6 should do the quarter mile in about 12.0-12.4 even if you can do it at 11.8 your car is still well behind some of the stock GT-R times posted below.

Don't even talk about mods as any mod on a GT-R will demolish the M6.
Just look at these numbers for a modded GT-R, and these are real life numbers.

Comparing luxury GC to a sport car is always a no win situation especially if you want to throw some curves in the race.
M6 is a nice car but comparing it to the GT-R which eats Porsches for lunch is crazy. Why don't you post up a video of your car beating a 911turbo and see what people say.
