Yeah, I never really had to grind because I always did endurances, but now I finally have to attempt 24 hours of Le Mans, but Im just at the beginning of level 34. Can anyone name any good xp races? Any race, just need to know.
Have no fear of the 24h of LeMans. It's like a religious experience!
The best way to gain XP is to drive the top race you are qualified for. But it depends on what you like -- Nurburgring, etc. What is your style? Do you like racing around with minimal effort, like Indy? Or do you like to grind "thoughtfully?" Then I would recommend 4 hours of Nurburgring. But I say go for LeMans. Get a couple mates together and pound it out one weekend. Red bull is not a sponsor for no reason!
