steering Wheel vibrating

My 2009 g8gt just started shimming the steering wheel a couple months ago. Thought it was worn tires. Bought new Michelin Super Sport A\S3 plus. Had the tires balanced and installed. No change, steering wheel shimmies at different times. Went to another place and had the front end alignment performed. No change. Decided to replace rotors and brake pads. Took to another tire shop and the got performed another front end alignment including adjusting rear toe. The rear 19x285 tires are toed now and that's not what I asked them to do. No change. Installed EBC slotted rotors and red pads. No change. In fact, it got worse. Not sure where to go or what to do. The tires have been balanced twice. I do not know what to do. I love my g8 and it use to drive awesome. Please help.

I would suspect LCA's are shot or worn suspension parts/bushings.
These cars are 8 years old now and things are starting to wear out under there if nothings been touched.

I have 105,000 miles on the car. The only thing I have done is add lowering springs about 5 years ago. Breaking has no effect on the vibration. The steering wheel vibrates so bad sometimes it's hard to hold, then all of a sudden it stops. New tires, three front end alignment's, tires balanced twice, new rotors and brake pads. Seems to have gotten worse.

Something is worn/loose in the suspension.

My wheel used to shake at random speeds usually 45-65 mph, but after the control arm replacements it has not done it since.

Anyone know what the mileage cutoff is for the LCA recall under warranty? Mine has 137K on it...

Also, I bought mine from a third party.. not a dealer.. so can I still get work done at any GM dealership? Or where would I go if it were under going to be covered by the manufacturer?

No, do you think the problem is the Control arm? I did not hear anything about a recall on the Control arm. GM did not send me any Info on that recall.

Were the wheels Road Force Balanced? If not, try that first.

Yes they were Road forced balanced. Twice. I have determined that while breaking the vibration stops, and turning the vibration stops. So I'm thinking about the suspension parts like you guys said. I guess I need to start with the upper and lower control arms. After that not sure.
