is it still possible to upgrade the rears to the 256mm vented rears off a 2wd VAG car?

my rears are grinding and there is already a lip on the discs.

yes of course. i'm also running 256mm rears.
i.e. golf 5 2.5 V5, polo WRC, seat toledo (5x100), skoda octavia vrs (5x100)

Is it worth it?
I mean: do the vented discs radically change the brakes performance and resistance to fade, considering that the front brakes do almost the 70% of the work?
Or is just an aesthetic upgrade?

they don't add a lot, if anything in stopping power. for that, a front-brake upgrade would be better. But you already have the 312/310mm vented discs at the front.

where a rear brake upgrade might come in handy, is when you do track days and that kind of stuff. A vented rotor is a bit better at cooling down, increasing repeated braking performance.

Thank you for the answer!
I was considering this upgrade, but then I realized all these things, plus the fact that vented discs weigh more than solid ones.
I think I'm staying with 232mm on the rear, since I'm not a track driver.

i'd say the rears do a fair bit

i did this upgrade on my 9n3 and it did make a big difference

it just made breaking more solid imho

i'm going to be modding my car soon aswell so the extra for calipers and carriers isn't too bad

would this work?

looks like an ideal purchase if it is right

ebay

make sure it's suited for FWD; AWD setups will not fit.

well seat leon cupra r was a FWD car

but in the list of cars it will fit both 2wd and Awd are listed

was the mk1 seat leon 5x100 (i guess it was based on the mk4 golf)

yes it was indeed 5x100 BCD, the same as the polo.
