What wheel and tire package are you running? Started with the original 245/45 Pirellis on the 20x8 stock wheels for the first 25K. Then ran 245/45 INVOs on the stockers. Recently mounted 275/40 INVOs on 20x9 Rohana RC5s.
Has the car been in any type of collision? Kissed a curb? Gone off road at a track? Negative
Has a run-out check been done on the wheel, rotor and hub separately and as a completed assembly? No, but I'm on my second set of rotors with no change in the vibration.
Is t the same shop that has road forced both sets of wheels and tires?
Each package was road forced at 2 different shops. Same vibration throughout.

Before we drive ourselves crazy, the easiest and fastest way to eliminate wheels and tires as a cause is to install two known good wheels and tires. Is there a 5th Gen owner you know that would loan you their front wheels for a ten minute road test?
If the problem still exists then we check the rotor and hub with a run-out gauge.
There is a remote possibility that the cause is related to alignment and toe. I have seen a few instances of this with the the G8 and her cousin the Camaro with worn tie rod ends and whacked toe. This is a remote possibility. Do you know what your alignment specs are?
