Here are some general recommendations for bolt lengths. Ultimately you are the one responsible for safely installing lugs and wheels on your vehicle.
> 3mm and 5mm spacers can use stock length bolts
> 10mm spacers for the front wheels can require 32mm long bolts
> 16mm spacers for the rear wheels can require 42mm long bolts
> 20mm and 25mm spacers for the rear wheels can require 50mm long bolts
The bolts for factory wheels are always Ball Seat and most all aftermarket wheels use Cone Seat.
All watercooled 4-lug cars use 12mm wheels bolts while watercooled 5-lug cars use 14mm wheel bolts.
