E46 Offsets - help I'm confused!

[anothere21323i]

Does anybody know anything about offsets and whether or not I can swap these wheels?

I've got a 2005 E46 M3 CS with 19'' CSL wheels. Front is 8x19 with ET47 offset, the rear is 9.5x19 with ET27 offset.

Question is, will a set of E92 M3 winter wheels and tyres (8x18 ET20 all round) fit?

Any advice much appreciated!

Thanks.

Fronts will stick out 27 mm further out towards the wings, which is quite a lot tbh. Rears will sit a bit more inboard than your current wheels.
