Yes, I'm aware of this.

That is why I prefer to tune cars to 1390 or 1250, for example. There are so many cars around those ranks, with Camaro SS' and Sagaris' at 1390, and Cobras at 1250.

Most matchmaking is based on how many people are in the lobby; if a lot of people are using cars at 1390, for example, then you will very likely get matched against them if using something at 1380.
