So I got a set of 15x10 Weld Prostars and to make them track legal (and safe too) I need to put longer wheel studs on. Id like to see if any of the readily available ARP ones will fit. I dont have any stock ones laying aroud to measure so I was hoping one of you might have one and coild measuer it for me. Take a look at this info on ARPs sight and let me know the measure ments according to their spec please? A, L1 etc... THANKS!

 

Can't help you with the measurements directly but at any parts store they have a parts book listing wheel studs and their knurl diameter, etc. How much are the ARP wheelstuds? Nismo makes 60mm studs (stock is 42mm) so I'd think those would be plenty long for you.

Also, I30tMikeD said his brother found an OEM wheelstud from another vehicle that works in his S13 and was really long, so if that wheelstud happened to work in the maxima too which wouldn't be too hard to imagine, you could get some longer studs for really cheap. I'll ask mike to ask his brother.

 

60mm is actually not long enough. I need ~3.25" because the hub on the weld rim is thick and the threads need to go into the hex portion of the lug by the diameter of the stud (.471")

Thanks for asking Mike.

 

I have some stock studs at home I need to put on soon I'll measure one for you when I get off of work.

 

3.25" sounds awfully long but here's your info.

Stock studs are
A= .56" (14.25mm)
L1= 1.65" (41.9mm)
L2= .3" (just knurl) or .6" (incl flat portion between knurl & threads)
L3= zero

 

Thanks a bunch!
