Sterling SUB AX4 Floyd Rose

I’m new here, I’m primarily a drummer…but also play some guitar and a little bass, I have a Sterling SUB AX4. I’ve swapped the pups with DiMarzio Air Zone & Air Norton already, but I’m thinking about getting a Gotoh Floyd Rose. A friend of mine told me Gotoh makes the Floyd on my AX4 so not to bother. I’ve read that Gotoh made them for the Axis model, but can’t find any info on if they also make the one on my AX4. Any help or info would be greatly appreciated, thanks in advance!!
