Just to add a little bit of info, any m12X1.5 stud will work. We used 90mm on our car with a rounded nose, with the rounded nose you cna put the lug in a gun and just zip it on. No need to start the lug by hand. The length is good for up to a 15mm spacer but obviously too long for stocker rims without spacers. Here's a link with all the info you need.
