Obviously it's better to use a compressor but for e30 m3 is there really that much tension in the front springs to worry about when removing with airgun?

Well got everything apart with the exception of one lollipop stuck on the conteol arm. Definitely recommend compressors it would have popped for sure without them. Btw i scored a complete e30 m3 front suspension with aluminum control arms for $450, hell yeah. My plan is to use existingsuspension on car plus this and have complete stock and track suspensions that i can swap out between

Significantly less, in fact. All that should be compressed with the springs in the strut are basically the dead coils (they just hold the spring in place). You're talking 40-50lbs of force at most. When you compress it 2-3 inches, there could be 600-800lb of force snapping at you if the half-worn out spring compressor you borrowed breaks (or the Chinese one from HF).
Not much really happens, nothing goes flying, and it's really quick. win/win.
