All I can say: EPIC FAILURE.
I double checked before the last race, racing soft. I practised on RS, I knew how they felt. Whatever was on my car during the race was not RS. They lasted 6 1/2 laps and lap times were 2:13-2:20. Pitted and changed to RS. Next lap 2:08. Looked at the review, it says RS. WTF.
I made the best of it but I am kind of annoyed.
