Can anybody tell me the standard offsets of Z4M Wheels please.
I'm on the brink of buying these http://www.bmautosport.co.uk/showroom/product_info.php/new-spoke-alloys-shadow-chromevery-rare-deep-concave-et33-rear-p-4030?cPath=51_27_135_47_301

and was wondering how the offsets compare to standard.

Thanks in advance.

Just looked at your planned purchase, smart. They are half an inch wider though, so this has the effect of moving the inside and outside edges 4mm apart, or closer to the suspension uprights and wheel arch.

The change from 30 to 33 at the rear will in effect make the outside edge 1mm closer to the outside and the inside 7mm closer to the uprights and centre of the car if you see what I mean.

The change from 40 to 38 at the front will move the outside 6mm further out and the inside edge 2mm closer to the centre of the car

Either way you should get away with it I would have thought
 
I thought they were

Fronts ET44 8.5" wide
Rears ET27 9.5" wide

That's what mine is on and fits just fine. With the offsets in the link they would fit real nice!

I looked into this and believe the std size is

5x120 pcd
18x8 et40 front
18x9 et30 rear

The centre bore I don't know.
