Quote from Vain :

I wouldn't like to see new cars, but I'd like to see the different cars in each class (for example RB4 and XRT) more equal in performance.
Every car should still have it's small advantage, but in a league over all tracks they should be quite equal.
That way we wouldn't always race with a complete field of the same cars, but have a mixture of the cars in one class. The only class where this is already possible is the FZR-class.

/signed. I'd like to see a race with 5-6 different cars, makes it so much more realistic for my understanding. Adding a Porsche 911 GT2 (or maybe RSR) would be damn cool, also Audi RS6 or RS-based GTR versions would be very nice to see.

Classes are enough in the game, but having more options in each class would make the game way more 'complete'.

/edit: This is more of a S2 wish than S3 to be honest.
