I have iforged wheels & no spacers, what size lugs do I need?

I think the thread is 14x1.5 but what length should the bolt be?
30mm? 38mm?

The head of the bolt is 17mm right?

 

I thought the 1.5" was a measurement of the Bolt thread, not actually the bolt length?
Im totally lost... so i need 1.5" bolt length? (38mm)

 

I think the 1.5 refers to the thread pitch? which leaves the question how long of a bolt should I buy? Maybe i'll go w/ the 38mm like you said rrrruben.

 

rrrruben: I think i should be looking for 29mm bolts right?

 

delirium, you are correct. 1.5 refers to the pitch. I deleted the misinformation. The length of the bolt, which in this case refers to the length of the threading (shank), is 29mm rounded up. The actual length is just over 28mm. Hence, some vendors will round down to 28mm, and others will round up to 29mm. And, That is my final answer. Good luck with your application.
