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.

Motorsport hardware sells stud conversion kits.

Turner sells longer bolts.

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.
