That should work, BFI has some good guidelines to go by when buying bolts.

"Here are some GENERAL RECOMMENDATIONS for bolt lengths.

**Ultimately you are the one responsible for safely installing lugs and wheels on your vehicle.**

Stock length is approximately 28mm

3mm and 5mm spacers can use stock length bolts

10mm spacers for the front wheels (STOCK WHEELS ONLY) can require 35mm long bolts

16mm spacers for the rear wheels can require 40mm long bolts

20mm and 25mm spacers for the rear wheels can require 50mm long bolts, however in some instances with 20mm spacers the 50mm will be too long and bottom out. Please check fitment before purchasing as all bolts and spacers are not returnable once installed.

The bolts for factory wheels are always Ball Seat and most all aftermarket wheels use Cone seat"

 

Thank you Nick.

 

Ok well I measured the Hub of of wheel. It was about 81.9 mm via vernier caliper. I cant use those hubcentric spacers he gave me as the small bore matches his volvo not my audi. So I went to local aftermarket parts shop and he told me they dont have that size (he made hte measurement) and I had to contact BBS directly. Any thoughts ideas on this?
