power commander and power commander

[spy13]

hello everyone, i previously had two 08 spyders which i sold back in 2010 and now just picked up a new left over 2013 RS-S. I ran the juice box in the past, however noticed that the juice box is not available for the 2013 RSS. Has anyone used a juice box or power commander on a 2013 RS-S? I noticed that power commander has the module but it is for the ST. (will the ST Fit)

thanks for your help.
