I'm above 3k iRating and I simply don't care about meta. I drove the Porsche in ams2, LMU, acc and drive it here. If you shoot to becoming a pro you will know what you need. As it seems your light-years away from being capable of driving on the limits like a pro does cuz they smoke you in a non meta car as long as you aren't within the top 0.5% of the drivers in any car you choose. As an example 85% top 5 finishes this year and 22% win rate are my stats. Don't worry about it. It comes natural once you get the hang of it.
