Hi
I've been running aftermarket TSW 15 x 7 wheels for almost 2 years on stock rear wheel studs.   Though there have been no problems the studs aren't quite long enough, and the nuts don't grab as much of the thread as they should. I really need t make this right.   I've searched the archives and have gotten some good info on Porsche studs.  Due to $$ I'd rather skip the Porsche studs and go with a generic stud.   What I still can't find is basic info on stud diameter, shoulder diameter, and thread pitch.  Anyone have this info handy? Ours is an '88 GL that came with oem alloys.

Thanks-

Gary
