Having a quick go on this now, most people are probably being put off by the first test lap. The car handles horrible on the track, no grip at all as said. I put in these options (for xbox controller):
Steering Dead Zone-15%
Accel Dead Zone-10%
Brake Dead Zone-10%
Steering sensitivity-5%
Acell Sensitivity -5%
Brake sensitivity-5%
Speed steering Sensitivity 100%
The car feels a lot better using these, just had a go on Spa and found it much easier to handle around the corners. Give it a try?
will have a go with these later, cheers for that as i found it quite hard to control with the xbox controller, fiddled with a couple of settings but still wasn't quite right....
