At first it does sound like you're referring to the Roush Stage2 though!
Roush did the stage 1 (body kit) on both the v6 and GT.
Roush did the stage 2 (body kit + suspension) on the v6 and GT
Roush did the stage 3 (body kit+suspension+ roots style supercharger and supporting mods) on the GT.
But from what you are describing and stated already, its a stage 2.
