Style 193 wheels. Good or no good?

[Joop1]

Hi all,

I am new on the forum. Just bought a beautiful Z4.
Well, there is one thing I would like to change: the wheels.

Personally I really like the 18”style 193 rims: http://www.bmwstylewheels.com/bmw/193
This is how they look on a E85:


But not sure if the front offset is a problem: ET 34 vs the normal ET 29.

This means the front rims will be 5 mm closer to the suspension (I would prefer not to use spacers).
What do you think? Only 5 mm won’t be noticeable? Or will it harm looks / ride quality?

Thanks!

Joop
