I gave you some serious suggestions. I used to be a purist and insist on linear pedal settings to go along with my linear steering. I later realized that, unlike steering, the brake pedal in real life isn't linear. The worse quality your hardware (and mine was way worse than V2's), the more you need to tweak the settings.
And for the record, there are plenty of people with Logi DF GT's that can run circles around me on the track. Good equipment doesn't make you a good racer...but it does make it easier to keep up with the fast drivers (AI or human).
