Re: obscure porsche question? (dfinn)
hmm, the only Porsches i've ever known that used bolts were made a while ago. the 4-bolt 924s are that way.
which ones have studs? well let me put it this way:
the 924 (5-bolt), 944 (all versions), 928 (all versions), 968 (all versions), and 1970s-current 911s all have wheels that are basically interchangeable with each other (except the offset is a tiny bit different). as far as i know, all of those cars use nuts to hold on the wheels, and there are studs mounted to the hub.
does that answer the question? sorry, i'm not a "wheel and tire" guy when it comes to aftermarket Porsche wheels. you can bet that if it's any of the models i named above, it has studs mounted to the hub, and you don't need bolts to hold the wheels on.
good luck!
