Reply to "GT5 Wheels on standard hubs/studs"

Quite a few owners have converted '71-74 Panteras to the GP 4 or GP 5 look, using 10-hole 10" & 12 or 13" wide factory wheels. Never heard of any stud length problems. If the wheel flange is the same thickness as the std Campy, there's no reason to use longer studs... unless for some reason the wheels you want are not factory and/or have thicker flanges, or you need spacers. Stock studs have large heads, and all the available replacements have smaller heads, so there may be some adaption required. With care, Porsche studs are longer & will fit in spite of being the next-larger metric thread (so none of your lug nuts will work).
