10mm shim gets you about 1 degree. 1mm shim gets you the exact same length of a stock arm. Hope that helps.

Shims are outrageously expensive for what they are. Google Demon Speed for shims. $5 for 1mm. $13 for 10mm. That’s for *one* shim.

I run custom made camber plates and GT3 arms on my 986. 3.75 degrees in the front (4mm shim) running 255 71R tires. 2.75 degrees rear running 285 71R tires. Setups vary on driver, springs, sways, course, pavement, Yada... Yada...
