there's this company called bec-tech, where i got some height adjustable struts from. i emailed the maker of them, and he said that they were meant to be used with the stock springs from a eclipse. he said that if i used the springs from a gs-t that it would increase my handling much more.

so i'm just wondering if anyone has anything to say about whether gs-t springs are better or not in comparison with gs/rs springs

Im pretty sure RS/GS/GST suspension is identical, and GSX suspension is slightly different.
