Aero is inferior compared to the gains to be made elsewhere I meant, I'm sure you understood that...

Of course when you have maximized the other aspects of your current homologated package you will chase aero.

Let's be realistic, stages have been won plenty of times without rear wings, wheel arches gone etc etc...

Have you seen Solberg in Mökkiperä or Neuville in Finland last year? :p
They didn't win the stage without a rear wing for sure.

can you name one, because i cannot remember...

Remember how much time Latvala lost in Wales 2014 without rear wing... The rear end of the car was all over the place.

S10 Impreza WRC had something like 100kg pressure at 100kph, that's quite a lot. Correct me if I'm wrong

Strange that John Kennard is not at codriver seats, and his place it´s occupied by Seb Marshall.

Even very small rear spoiler on R5 Fiesta makes big difference, very difficult to drive without it

Definitely possible, maybe even more. A tiny formula student car from my Alma Mater is able to produce 60 kg downforce @ 60 or 80 km/h by it's wings (I don't remember exactly) and that's something as small as a go kart and the force is growing with the speed squared.

i believe it is quite the opposite.

formula 1 cars need to be able to reach speeds of over 300km/h, so they actually cannot use really big wings.
they have long straights, and few corners, so they rarely have a lack of traction. but most importantly: without a high top speed they can't overtake.

rallying is completely different. you often don't have enough traction, but very few moments where you hit top speed. and you don't need to overtake.
so here it is much better to sacrifice some top speed to gain traction through a much bigger wing.
