Safest bet is OEM wheels although they are costly. I run 19" 403M in winter and 20" 405M in summer. these are both staggered setups with 8" front width and 8.5" rear width. If you are lowering car too far and installing very stiff springs, the 20" wheels have very small sidewall size and stiffen the ride considerably, they get damaged easily. I have pinched tires which cause tire bulge (lucky no bent rims) however I only have the Eibach Pro Set Springs (10% stiffer than stock). 19" are much safer IMHO, cost less and still look great. Just make sure you maintain the OEM offset, stay at 8" width in the front. If you have xDrive AND are going staggered, pay special attention to the sizes to maintain within 1% outside wheel diameter to prevent any drivetrain issues!!!
