Post pic of your setup ... I like to see how are they protrude the fender.

 

X2!!

People run 20mm spacers on stock ET45 wheels, so I don't see why Et20-25 would not fit...

 

Fit? Of course, as long as the correct bolt pattern & with centerbore size = 72.5mm (even at bigger size you can use slip ring adapter) any wheels will fit ... now are they gonna look proper?

For example pic #8 (or #5) on this thread -> https://5series.net/forums/dealer-pu...12/#post195085 is an ET20 front at only 8" wide (I don't think 19" diameter relevant) already not flush looking.

I know the meaning of proper look different with everybody but being an xi/AWD model that sit higher and wheel/tire stick out protrude the fender will just end up look like a 4x4 truck.

 

Here is the pix of the wheels I mentioned. At the time of those pix the tire sizes were 245/40 and 285/40 but i changed all of the tires to 255/40's and ran with that for a while. The front rims didn't stick out like everyone has been telling me. But those 285 tires on a 10.5" rim sure did, but when I did put the 255/40's on it you couldn't really tell anymore. Since these didn't stick out in the front M5 wheels will be perfect.

 

Not sure 'bout didn't stick out ... here's M5 wheels on xi/AWD:

... sorry not my cup of tea ... but hey to each his own.

 

Those M5 wheels stick out some. I see how why it would bother some people. But the rims I had on my car did not stick out like his. So if someone puts 9.5" rims all around but with a different offset on the rear the wheels would sit flush with the fender wells. I myself can't stand seeing cars with wheels inside the wheel wells it Iooks ugly to me. But to someone else it might look sweet.

 

Is your car lowered?

If not, you should be fine.

If so, then you may need some minor fender rolling.

I have 19x8.5 ~+35 w/ 225/40 & 19x10 w/ 255/35 ~+19, and the rear fenders needed to be rolled a bit. Lowered on H&R Sports.
