OEM Lug nut size

Hey guys,

So I was about to get spacers for my car and I was ordering some bolts but I could not find the original size of lug nuts. I'm looking at getting 10m front and 20m rear. Does anyone know what the stock size is and what size extended bolts I will need?

Thank you,

So I would need 40mm in the front and 50mm for the spacers right?

Not sure..? I would call your dealer. If you give them your VIN, they should be able to tell you the exact sizes.
