I have a 89 cabrio gti and i wish to put some design 90 porshe alloys on but i have noticed that some come in 6.5, some in 7 and some in 8 inch width not forgetting i have to put adapters on them whats is the max width i can use...

6.5 on the front will be ok and 7 on the rear ok, but you will have to do some arch rolling and if you have a clipper kit, start cutting the insides of the arch kit as the wheels will cut into these...
