BRZ: i highly doubt you have 2 degree toe-in, car would have been nearly undriveable if so with insane toe wear. If camber is ok to change in degrees, toe is adjusted with less then tenhs of degree, and difference already often can be easily felt. For example my rear toe-in is ~ +0.12dg each wheel, 0.25 total.
I'm rather thinking that measurement unit in your case is in "mm" (alignment racks usually can be changed from degree fractions or minutes to inches or mm. Unit imho should be there in printout). You can use online toe calculators like these inches-to-degrees
. 2mm(if for each wheel), 0.15748" total toe for 215/45/R17 outer diameter is ~ 24.62"
, so for one wheel in degrees +0.18dg, total +0.36dg (or half of that, if 2mm was total toe).
GoodYear Asymetrical 5 are good road tires with grip on PS4 level (with maybe a bit less wet grip).
Imho your setup should have enough grip and if toe is like that, it shouldn't be tail happy, certainly not so if not driven on public roads like on track or doing something to intentionally throw off grip. Need more info, to decide what else might be off. BTW, does toe have positive + sign before value in printout (usual way to tell it's toe-in, with negative usually meaning toe-out)?
