I've just had a bad experience when racing formula B at Donington (career mode). Somewhere in the race it started to rain and I lost the lead. I even ended up in the last position. AI and me pit for rain tires (wet compound) but it still seems the AI have much more grip than I do. I also increased my downforce but it stays too difficult for me, while I've almost no problems in dry conditions. Is there someone who can help me out?
