A little less grip would make the game feels more realistic

I fully agree with you.

I think less grip would be beneficial but also some work on the grip limit and how it starts sliding under power. It is literally impossible to do a hairpin in a proper rally way. You cannot throw the car while making the rear-end slide so you avoid understeer. Not even with the handbrake or power sliding on the exit. This feedback is based on Rally1 and Rally2 cars, but I heard from other people that RWD are suffering the same issues.
