Thanks kamui for the OP.
Forgive me for asking but are you driving with abs on in game?
I am far from professional driver but in my experience of whipping my personal vehicles around highway on and off ramp in the states, abs on(even at 1) is totally unrealistic. At high speeds road cars should lock up quite easily with minimal steering and breaking input, especially with changes in road height. I've found that abs 0 is closer to real life driving, imho.
Hate to bring a wish into someone else's thread but there is a big pink elephant in the room staring at me. When will we be able to change the width of wheels and tyres?
