The comment about the Mines car being faster than the JGTC cars was ONLY in reference to acceleration and made by 2 JGTC GT500 Drivers.
I'm happy to accept this statement based on the fact that the Mines car produces 600ps & 60kg-m (as taken from GTR Magazine) and the GT500 cars are regulated to 500hp. Also factoring in the extreme engine response of the Mines GTR makes it 1 VERY VERY quick car (without the need for mega hp)
