I just did some laps last night and I can get 5 good laps with lap 6 about 50% worn and lap 7 about 60-70% worn using Racing Softs. I think it will be a toss up between a 2 stop and 3 stop strategy. From what I’ve gathered on GTPlanet the Racing Softs wear much quicker than Racing Hards and Racing Mediums, but they have such a large advantage that they still are faster even with the extra pit stops. I haven’t had time to confirm this for myself though. I’m interested if anyone else has experimented.
