how many gig's does the season pass use?

just wondering really intrested in buying it but i have to know how much gigs i need for it all.

The actual pass is only 108kb, but each of the packs you get with it are what takes up the room. Each pack is around 110 MB and there’s six of those. So, you’re looking at about a gig or so.

Thats it thought it’d be more looks like i’ll be purchasing it very soon.

Yeah. It’s mainly the content from Disc 2 that takes up the majority of space.

so does the season pass include the porchse pack aswell or just the 6 monthly’

Just the monthly. You have to buy the Porsche pack separately.
