I was at 62 % with the tire set up i had. I was told the left rear was too large go to something smaller. I ran something like this years ago but i don't remember what kind of stagger i had but it did ok.
I candrop the left rear cassette some. I forgot about that. I have a little weight to move but not much. Right front spindle is down a little. I will put on the scales and see what I have. Picture of left rear.
