Oldish thread, but I thought I'd add a bit... I believe that the motorized spoiler requires a different coupe trunk lid section assuming it is a "unit" that replaces the SRT6 directly... if you want it to sit flush like it is supposed to be. Gotta have room for the motor mechanism, wiring, and take out the SRT6 fixed wing... Sure sounds like a lot of work, and cost to have a lesser aerodynamic show piece. But hey, folks have done less with more $. I think the SRT6 fixed wing helps break up the boattail rear end a bit sort of the way the Infiniti G35 sport coupe has their nice looking rear wing to help give the *** end a bit of curvature rather than a drop off... It's a matter of choice though...

If you trade up, just work out the costs and figure out how much you want to spend to have it a "custom" SRT-6.
