I found that the S4 doesn't need to be pushed as fast laps can be made just by being smooth with it. But if needed or you want to drive aggressively then the car is sooo forgiving that it is possible. It didn't even want to loop out at the end of a carpet straight going onto polished floor corner.
I had a go with a bj4 (also a v good car) but did find the S4 suited my driving better. I could push more on corners, and it looks bloody gorgeous as well
