i have installed F30 staggered rim on my E46 sedan.

after much calculation, i decided to install the wider rim at front, because i afraid offset ET34 (8j) may be too wide at front.

At first, the tire shop was reluctant to install the wider rim at front...
finally i managed to convince them.


Details:
Front rim : 8.5j ET47 (F30 rear rim staggered)
Rear rim : 8j ET34 (F30 front rim staggered)
Tire: 235/40/18 x 4pcs

Rear fender rolled before installed rims.
No rubbing, perfect.

my questions:

1. The front rim edge is only 5mm to touch the absorber, is it ok ?
(tested and no rubbing so far.)

2. The wider rim will have extra weight installed at front. is it ok ?
(personally i think ok. i think that is insignificant extra weight.)

I would honestly swap them to the proper locations. That way you would restore handling plus have more clearance against the front shock. As well as not have that weird poke in the front.

i used to have square setup, 225/45/17 ET34 (8j).
pics as below.
The front looked sticking out a little.

Now, i already have 4 pcs of 235/40/18 tire that removed from other car.

in front ET34 (8j) 18" will be the same offset.
235/40/18 will make it sticking out more 5mm.

the rear of ET47 (8.5j) 18" will be 13mm pushed in.
235/40/18 will make it 8mm pushed in in total.

On paper, that will make the front tire sticking out too much, and the rear tire pushed in too much.

Update:
i have checked with the mechanics. The mechanics says the 5 mm clearance is good enough.
