PNW, I would guess Pacific North West....
you dont need a spring compressor for coilovers.
go to harbor freight and gets some tools buddy, itll be $300 for all the good **** with lifetime warranty. its also good to have around.
With most coilovers, you wouldn't need compressors because the coilovers would come with top hats. The problem here though is that most of the coilovers out there for the Sonic don't come with top hats so you would want spring compressors to remove and reuse the oem top hat.
idk how Ubryaj did it, but better safe than sorry In My Humble Opinion. Springs can be dangerous if removed improperly.
