These are what I have .
B8 le mans 8.5j 19" ET43 with 235/35 tyres.
I had a slight issue with tyre rubbing on the inside edge against the front strut so added a 5mm spacer to the fronts and 8mm on the rears just to give it a more staggered appearance and its been spot on, basically I have made an adjustment for the added 6mm extra rim width on the inside rim edge so it back to oem width , well from an inner wheel arch position that is.
the outside rim is now ET43 + 6mm for the extra rim width + 5mm spacer = ET32 from a poke standpoint.
