The TRD springs I think are slightly different than the Eibach (edit: pro kit for clarification) springs but are made by Eibach. You WILL need aftermarket struts so if you are gonna pay to get them installed, you might as well put them in at the same time. The TRD struts are the exact same thing as the kyb gr2's so if you were planning on getting the trds, you could get the kyb gr2's for cheaper.
