Offset Question on Z4 and E90

[gwatson]

I am looking to fit a set of alloys from the new E90 3 series.

The offsets are:
18" x8" et34 front
18" x8.5 et37 rear.

I understand from another forum my current standard BMW Z4 107 style allows are:
18" x8 ET 47 front
18" x8 ET 50

So will the E90 wheels fit my car? I don't want to have to roll arches etc etc. I know some people fit spacer on the rear of the Z4, will a bigger offset give the same look, or will it be too big? What about the front?

What about fitting a set of replica's with an offset of ET40? The rears will only be 8", will that cause a problem with 255/35 wide tyres?
