Looks nice wayno! The concave looks a lil deeper on the front of the bmw than yours, I'm guessing the bmw can fit a wider rim/lower offset but seems like you could of gone a little more on the front too. I'm looking at the Rohana RC10 wheels in matt black, 20x10" and 20x11" on rear, not sure on offset yet but you can choose your offset as its made to order. Can use this offset calculator that's handy and get a measuring tape out which will give some idea: http://www.1010tires.com/WheelOffsetCalculator.asp
