Important, is difference, this size in e82-e88, is diffenrence than e87-e81. About 7mm is wider the e82-e88 rear, than e87-e81.
So these are two difference sizes.
It's looks a simple question, but I haven't found the answer.
You have to look at this space...
If we install the same size front and rear, for example... 8x18 ET40.
How many milimetres will finish more into rear than front?
I will insert a pic:
This is a 8x17 ET20. Front and Rear.
I think there is a difference of, aproximatly, 10-12mm more into rear than front with the same sizes front and rear (BMW install for example...in e87-e81, 7,5 ET49 front and 8,5 ET52 rear, this is... 9,7mm diferent between front and rear wheel).
Has anyone measured?
Because if we install for example, 8,5 ET38 at front, and 9,5 ET38 at rear (12,7 mm difference) aproxmatly both wheels, front and rear, finish with the same difference.
