Hey guys. I was looking into rims to get for my GTI for Christmas. I stumbled across some 911 997 reps for an awesome price. Here are the stats; 18x8.5 +57 front and 18x9.5+46 rear. I have done some searching around and I know there was a guy who ran these on his GTI, but what exactly would I need to make these work on my car? Spacers, adapters? I'm totally new to buying a new set of rims..
