With 8.5" et47 (400M), the centre of the wheel will be 13mm further IN compared to the 8" et 34 (397). With the additional 0.5" of the wheel, it will have extra 0.65mm on both inside AND outside. So the overall effect will just be 13mm - 6.5mm = 6.5mm, i.e., the 400M wheel will appear 6.5mm further IN compare to the 397 wheel.

Please correct if I am wrong.

Yeah you are correct, 1/2 of that 13mm will be on the inside. The 8.5" wheel at ET47 will sit 6.5MM further in compared to my 397s. The wider tire however probably negates that, so still nearly identical as far as clearance goes I think.

Look forward to the pics Shiv.
