Thanks. Some comparisons:

1M OEM
front: 19 x 9 ET31
rear: 19 x 10 ET23

New wheels
18 x 9.5 ET41

Calculated results:
Front: 16mm LESS clearance on the strut side, and the outside edge of the wheel will RETRACT 4mm
Rear 24mm LESS clearance on the strut side, and the outside edge of the wheel will RETRACT 12mm

I know I lose an inch in diamater so I guess the question remains, will they fit?
