hey, i have a a4 avant s line on a 57 plate
it currently has the 5 spoke 18x8 ronal wheels on which i believe are ET43
i now have some new 18x8 wheels that have an ET of 57
i would like to have the wheels sitting flush on front and slight poke on the rear
just wondering does anyone know what the offsets will be to make this happen so i can sort out spacer sizes?
