How do you use spikes currently? (10.3, Freccia)

I test drove the Freccia to see how spikes do and they are almost fully incapable of killing the T-90A in test drive. How are you meant to use these? Am I doing something wrong? If they’re this bad why are these vehicles such high BRs?

Shoot the side as now IR ATGM has the Weapon lock off-set to the center, it should help, also, if the launcher are able to follow the vertical guidance of the auto cannon, try to aim down, if I’m not wrong those are the same behavior on the Israeli Namer 30.
