The C5 Z06 has a variety of settings involving traction control and what they call active handling. Traction control prevents the rear tires from turning into smoke and active handling helps keep the butt in the back. If I remember right, you can have both turned on, both turned off, or TC off and active handling on. I typically drive with traction control turned off and active handling turned on.
Even in that mode, you can get the back end to slide around a bit, but not so much that you eat some tree or guard rail. More or less it gives you the ability to play, but not have to worry about wasting $50K.
The active handling has little effect on the front end grip, primarily controlling the rear end from around on you, similar to what we see in the game.
Overall, I remain confused a bit by the physics of the game. I took out the Huayra for some challenge at DRC on racing hands. The previous time I drove the car, it was with sports sorts. Being at my favorite track on racing hoards, I expected a cake walk. I couldn't have been more wrong.
The tire noise was the worst I've encountered in the game and the grip seemed worse than on sports softs. In addition, I drove a couple Lotus cars in the international B races and I can't imagine those cars were anything close to reality as I could barely complete a lap without spinning and sliding all over the track.
I decided tonight that once the I finish all the offline stuff, I'll never race most of the remaining MR car. I can control the Ford GT and I think Ferarri has some I can handle, but I'm not going to change the way I drive to suit the car. If the car doesn't work for my style, then fuck it.
Same goes for certain tracks. If I don't like them I won't visit them anymore. I enjoy racing with you guys (even though I have been around much) but game is supposed to be fun and for me tnat eliminates a lot of cars and several tracks. It's not a complaint, just no reason to race if the combo doesn't work with my style.
