hello, sorry I can't help on the wheels mate although they do look familiar, your car looks like a great example though, epsecially for free (well almost... I'm sure you paid in grazed knuckles back ache etc. swapping out your buddys civic engine

)
like yourself I'm new here too, not owned any golfs for a looong while, (my othering 4-wheeled passion is early porkers) but I just picked up a late 8v gti for daily driver use yesterday, and i forgot how great these cars really are.
