Baer SS4 with 15 inch Rallyes?

[69CudaFan]

I have the 15 x 7 with 4.5inch backspace. I measure with the template from Baer, and it seems to want to hit the weld on the inside of the rim. I am wondering if a 1/4 in spacer will cause me issues taking it from hubcentric to lugcentric. Am I nuts to ask?

Measure distance from center of hub to top of caliper, I’m sure Baer has a schematic on their site with the info.
