Longer Wheel Studs

[Bav3.5]

What is the length of the stock rear wheel studs on an e3? For longer wheel studs, there are references to using the ARP 100-7715, but i'm trying to figure out how much longer they are compared to stock. The ARP's have the following specs:

Wheel Stud Thread Size: 12mm x 1.50 RH
Knurl Diameter (in.): 0.558 in.
Underhead Length (in): 2.600 in.
Knurl Length (in): 0.275 in

Basically, I'm considering a 15mm spacer and i'm wondering if the ARP is sufficient.

Thanks

Tim

Well, the ARP's mentioned above worked out well for the rear. For my '72, the stock rear studs are 47mm total length with an under head length of 44mm. Hope this may help someone in the future.
