wheel advice

[the stripler]

Hi,
Can anyone advise if these wheel fitments below will go on my 56 plate z4 SE 2.0. seen them for sale

Genuine staggered set of mv2s with tyres!

Fronts are 18x8j et47, fitted with 225/40/18 matching Bridgestone tyres with about 5mm tread.
Rears are 18x8.5j et50 with 255/35/18

don't know if this means that I will need to change the springs etc as my car currently has 16" wheels on and look crap. Can anyone offer any advice.
thanks

Hi, a lot of members on here use 18" wheels, so these should fit your Z, I run standard 17" on my car.
I know some on here run 19" but I think you may have rubbing issues with that size.
I'm sure some one will give you more info
