So I have a set of staggered wheels off of a W222 that I want to install on my S212 but it looks like I need longer lug bolts as the new set is thicker. The specs are as follows: Current 8.5 x ET48, New 8.5 x ET36 and 9.5 x ET43 any info is appreciated! Attached is a photo of my current lugs through the new wheel.
I hope you calculated offsets to start with?
There is company, who specialize in custom wheel bolts. Don't have link handy, but lot of them on forum already.
What you need to find is what radius the new wheels have.
Than stick original bolt into original wheel and measure how much it sticks out on inner side.
Than repeat the bolt measurement on new wheel and add the difference to original bolt length (shaft only) to get what length you need.
Final confirmation should be counting the turns. You should have at least 6 turns before bolt stops at the seat.
When you have more than 10 turns, you risk screwing your parking brake. Front hubs are pretty tolerant to long bolts.
