Toe when lowering?

Im not sure but it appears that the rear wheels on my 1990 240sx are toed out a little bit since i put in my coilovers and dropped the ride height. I know this can be the case with cars that dont have double wishbone suspension but im wondering if im just paranoid or is this what happens with the s13 as well? If so what is the best way to correct this?

Probably have some toe out

Best way is to get an alingment.
