7x15 BBS Mahle wheel bolt size

[mistermatter]

Just tried installing a set of original 15” BBS RA Mahle basketweaves on my 1979 Baur but the bolts I have are too short. Can anyone tell me what the correct bolt size/length is for these? Any help appreciated. Link to image below. Thanks!

I have a set on my car and I have IE's 80mm extended studs and I don't have much extra stud left over when the wheel is on.

Really pathetic how they don't bother to actually give the length. You're supposed to guess based on the p/n I suppose.

The stock wheel bolt extends 21.5 mm out the back after it passes through the wheel. That's what you want. If you use a thicker wheel, or use a spacer get a longer bolt, such that it will still extend 21.5mm (or thereabouts) out the back when put through the wheel hole.
