Spd Kilz Z06 (430rwhp) vs TT 350Z (430rwhp) vs McLaren SLR
SLR beats the Z06 by one car, and the Z by 2 cars. For the equal amount of whp and being 200-300 lbs heavier than the Z06, I would say thats impressive. I would say both cars are extremely impressive staying so close to the SLR.
So there you have it 2 Z's race, and the SLR prevails.
