Topic. I searched the forum and found one other topic with the same question and the answer was yes, but that was pre-patch1.04. I tried a race earlier in a GT and the number of wins I still need did not change. If it matters, when I started the race solo, it didn't give me an option to choose which class of vehicle I wanted to use, I used my custom GT.
