while using only normal cup 2s, that's a very mighty time.
interesting insight is that Steve asked Porsche to dial out the understeer, and it was faster than the gt3 on the same tires. I suspect why it's slower than the gt3 on other tracks is partly due to the car being set up a bit more safe and understeer-prone, normally.
