Actually I ordered mine with the 108mm centerbore because that is what I was told on here, but they were WAY too big when I put them on and I measured the spare tire and it was at 100mm.
THEN when I took off the STOCK 18"s I measured their center bore and guess what? It was 99.5mm. I don't know where this 108mm came from but it is wrong. Stock centerbore on our wheels is 100mm.
