I have two suggestions involving DRS. First, is how about a second DRS zone in the tracks as it already happens in real F1. Not in all the tracks only in those which realy have a second zone.
Second, is how about enable DRS and KERS in rain wheather races. The reason KERS and DRS are disabled in real racing is to reduce the possibility of an accident. Since there are no accidents in iGP (and there won't be any as it looks like) i dont see a reason for disabling KERS and DRS. The only think that happens by disabling them is to eliminate the chance of an overtake.
