Will this match z4 m coupe?

Simple answer is no.

The fronts will stick out 39mm more than OEM, the rears will extend 26mm more - so you'll likely have rubbing/clearance issues on the arches.

Plus, the E39 used a different central hub diameter, so it will at least need a hubcentric adapter to stop it wobbling/damaging your hub.

For reference, OEM sizes are 8.0x18 et42 (front) and 9.0x18 et30 (rear) - and there's a handy offset calculator available here.
 
Good answer! :thumbsup:
But sad... ok but can i use lower ET´s because stock is leaving to much space

Exampel. et 29 fron and rear or is it to good, where is the limit? I dont understand the calculator :headbang:

Thanks!
 
If it's just for looks, then get a 10-15mm space fitted with OEM wheels.

The smaller the offset (actually negative offset) then the more the wheel moves away from the centre of the car. Add this to 1/2 of the extra width of the wheel and you can work out how much more it moves away from the centre.

So if you have an offset that is 20mm smaller, and a wheel that is 25mm wider, then the total amount further away from the centre of the car is 20mm+(25*0.5) - 32.5mm.

The other thing you'll have to factor in is tyre sizes - as you'll need to work out the reduced profile to keep the rolling radius the same as a 225/40r18 OEM tyre would change to 225/35r19 one - but with a wider wheel on the front you'd also probably fit a wider tyre such as a 245/30r19.
 
for conservative fitment that looks good work with these offsets front 8.5"+35 Rear 9.5"+25 give or take alittle these are pretty much bang on for a z4m..... in 18" or 19" fitment......
 
Ok, i have now found my dream rimz for z4, will this match?

You'll need spacers on the front wheels, about 15mm. The rears will fit spot on. This is based on OEM M3 wheels onto a Z4M
