extended length lug bolts

B-52Gunner · 12-01-2010, 06:07 AM

What length extended length lug bolts do I need for 12mm and 15mm spacers? 39mm shank? I have some RAD 12mmx1.5 39mm shank at home and want to know if I can use them.

Thanks

Ideal shank for a 12mm spacer is a 38mm but if you can certainly use the 39mm shank without any problems. Ideal length for the 15mm spacer though is a 41mm shank. But since this isn't a perfect world, you can't always get what you want. Any bolt shank within 3mm's of the spacer size is absolutely fine.

Thanks again
