So this is pretty dumb, but I got the Yeah Racing rear toe plate. And the only way to get less than 3.5 degrees of toe in, you have to grind some rather large chunks off. Even though the instructions show the inside most lines are 1 degree of toe in, there is no possible way to achieve this with the toe plate.
Just thought I'd throw that out there in case anyone was interested.

EDIT- Upon actually trying to use the piece I've discovered that it's only the lines that have been printed wrong. The inside most position appears to be either 1 or zero toe.
I'll throw it on the setup station to make sure.
