I have a friend looking to put some spacers on a newer vantage (2019) and needs to buy longer lug bolts. Would anyone happen to know the specs on these lug bolts ? I can tell that they are ball seat (not conical) but I've seen some sites say the thread size is M14 X 1.5 and some that say M14 X 2. Also just to confirm is the outer diameter 23mm or 17mm ?

Thanks in advance for the help.

 

14x1.50mm with a socket size of 17mm

 

Thank you so much !!
