I went and revisited the Lambo earlier today. Actually, I built it out as A850. With street tire, and no aero.
It does have a ton of grip. With the way it was built for A Class, I had to put postive toe in the rear to get it to rotate. On the stock engine, it was almost impossible to light up the rear tires, unless at the starting line.
Now it still lacks the top end in S Class. But the grip is still there.
Checking out the competetion, the 512TR, It is just as good as the top S Class Thunder cars. Man it moves. It was nessesary to put a turbo on it, but there is no lag.
