rough change is about 15mm, so 18x8 +35, coz mine went down from 9 +20 to 9 +5 when reversed

The face is 1/2" so a 1/2" from the outside to a 1/2" to the inside is 1" of difference divide by 2 = 12.7mm of change

12.7mm + the width of the mounting flange on the barrel I would assume too. That would be about 3, 4mm I would assume if they are the same as my Super RS.

My answer is correct, but my work is wrong.

It is just like adding a spacer. Should be 1/2" total if I remember correctly. I just measured this a few weeks ago. I dont think the face is exactly 1/2".

I will measure tonight and let you know

Pictures please!

And since we're on the topic of LMs. I have +35 18x8 LMs, and want them to be +40. How do peeps feel about shaving them down?

if you mill them, and the machinist knows what he's doing, it shouldn't be an issue.
