the stock 18s suck
too small...too dark...too much going on.
My E93 M3 came with the 18s, and after using them for 1 winter. I sold them and grabbed a set of OEM 19s. Best decision I ever made
2016 BMW X5d - Black Sapphire on Terra
2016 Range Rover HSE TD6-White on Ivory
2010 Audi R8 V10 Coupe 6MT-White on Red - gone but not forgotten
