Golf MK5 GTI AWD conversion from a MK6 R

Hello folks, i have a big question, i'm gonna do an AWD conversion on my MK5 GTI and get the parts from a MK6 R, does any one know if the rear subframe is bolt on on the mk5 GTI, also does the MK6 R has a haldex gen 4?

Thanks all!

You’ll have to shorten the spare tire tub. And go to the saddle bags style fuel tank to accommodate the components. And that mk6 r gen 4 haldex. Mine is gen 2
