550's should be more than enough for an 18G, but what year WRX ?

Sti Pinks make about 505cc at 3 bar, and 550cc at 3.5 bar fuel pressure.
They should be fine for an 18G. Worst case you'll need to up the fuel pressure, which would require an adjustable fuel regulator if you don't already have one.

There are no disadvantages in going for the bigger injectors apart from the cost of them.......your WRX injectors will be maxed out !!
