My goal was to run a new R10 in stock form using racing soft tires with or without aids in the real circuits tour seasonal event (662 Hp/679 pp to start with, gradually increasing as the engine breaks in), I can win all but Fuji, so far the best I can do is catch the lead car in the last turn but not pass it before it out-accelerates my car to the finish line. I'm not happy with my tuning on any of the courses but at least I can win with them - except for Fuji, either too much oversteer or the back snaps out under acceleration in the low speed corners (I'm a level 40 driver and it's killing me that I can't figure this one out). Not happy with any tunes that I have found posted either. If anyone has a suggested tune or other helpful advice please let me know - thanks
