Thanks guys, I'll try to learn how to tailbreak. I'm driving US (14 front, 13 rear) with front wing at 20 and rear wing at 9, MGH-U to motor and MGH-K to hotlap mode. I've tried setups from youtube posts, but they don't seem to bring me much. I guess it's driver quality before anything else. I experienced while testing with the ACF1 and Mania.ru car mods that It's way easier to keep them on track. I have no difficulty whatsoever to keep these cars between the lines. As for the Formula Hybrid, I always seem to be having heavy understeer (even at max wing settings). I tried adjusting my wheel (TS-PC Racer) by bringing the Gamma down, also tried to set Steer Assist down to 70 to have better grip on the wheel, but nothing seems to help me get rid of the understeer.
