Why do you need wheels that wide, or is it just for the "LOOK"? I have 17X7s on my VW with a turbo 2276 and that is enough rubber. Be careful adding all that weight to your wheels, you WILL notice a difference in acceleration, handling, and braking for the worse.
It is not just wide wheels, or body style, but track width that makes flaring a Ghia something that some people might want to do. 17X7s on a Ghia are tricky without flares, and add very little track width. Autocrossers prefer 8" wheels for that particular type of driving...all depends on what you want. And some people think a nicely flared (widened) Ghia is better looking than a stock one...imagine that.
This is an older thread, but I still have questions...
Has anyone fit 9" wide wheels under the rear of a stock Ghia? I have a set of 17"x7" Porsche Cup 2 wheels now, and I was thinking of buying a pair of 9"s for the rear, and I was wondering if someone has ever fit them. They all have a 55et, I know the 7"s will fit now, I was just wondering if I can squeese another 2 inches out of the stock opening. I just measured my wheels now, laying them flat with a straight peice laying accross the front, and they measure 8 3/8" on the width of the tires (205/50R17). All I need is 3/8ths of an inch and a little more for tires.
Between tire choice and spacers, I think they just MIGHT fit. but I'm not sure, I should probably measure everything again.
