I bought these wheels as a winter set and the offeset was in the mid 30s...(cant remember exactly, maybe 35) and a 18x8 width. It did not come off a X1/X2 platform so the offset was on the more aggressive end for this car.
A tiny bit of poke but I think it looks pretty good. Gives the car a wider stance. Obviously if I were custom ordering wheels I would have gone for a little more offset, especially on the rear.
