Back in the eighties, when I bought my 914, I wanted to add 930 flares which are closer to round than stock 914. Since then, I've noticed that cars haven't had squarish fender openings since the 60's and early 70's. Since then, they are all closer to radiused openings. Only trucks still have straight(ish) tops to their fender lines. Ther are exceptions, but not many. Check while you're standing in a parking lot, or driving around. So the 914 fenders are definately dated, along with the rest of the car (and I mean that in the best of ways, I still find my car's lines beautiful). Neo's comment is right on, to update the fender wells, the rest of the car's styling cues need to be brought along as well.
When I came to this realization, I bought GT flares and 7" and 9" Fuchs because, now, to me, they just look right. Don't get me wrong, I've seen altered 914's that are beautiful with different looks, but I really love the GT theme (but not 916 bumpers, that's a different conversation).
Just my $.02,

Now if I could just get all my parts out of the garage and onto the car...
