VRSick,
you can fit those on your dub with the correct backspacing on the rim (which most porsche rims have) without wider fenders in the front (though it depends too on how low you are going to go).

If you go to a wider rim in the back then the front, you will either have to buy wider rear fenders or narrow the rear suspension. Because I dont believe a 8.5" rear wheel will fit with the above mentioned mods.
