I had a co-worker ask me a question: He was driving his C6 Grand Sport (new to him, bought it a couple weeks ago) and when turning aggressively he experienced more turn in than he anticipated. He is an experienced driver of muscle cars and understands oversteer/understeer well. He said he felt like the car was pulling into the curve. He had to steer slightly out of the turn to compensate. Is this a common driving effect I have just never felt or is this something else?

Data: Michelin Pilot SS, temp 60°F, 60 mph on 40 mph roads.
