What? Tsukuba? Tsukuba is flat go cart track. The only thing it proves is how much big wings and spoilers help in a lap time. Road Atlanta is just as bad of an example. It is a much shorter track than the ring and the back straight would let the Vette's top end walk away from the GTR. Even Laguna Seca can't stack up to all around test that you get from the ring.
The Nurburgring has over 170 corners and most of them are off camber and are always changing elevation. This means you are peddling the throttle most of the way through looking for grip.
There is only 1 true straight away. Don't let all the lastest nonsense of publicity the ring has gotten in the past few years mess up the fact that the Nurburgring northloop is the best race track in the world. It was never sanitized like modern GP tracks and it is still the ultimate challenge to a driver period.
Seriously, most of these turns take more bravery to take flat rather than just skill.
