slight off balance feel at 70-80mph
I love my 2011 GT/CS, but I've noticed since day one, that I get this 'out of balance' feel while going 70-80 mph from the center/rear of the car. the steering wheel doesn't shake back and forth, but I can feel it in the gas pedal back through my seat. It gets pretty smooth when I go slower (40mph seems great), It does not seem to get any worse the faster I go, I got up to 100mph and it seemed about the same or better than 70-80mph.
The reason I don't think the rear tires are out of balance, is A), it was like this since day 1 - so the factory would have to have messed it up (unlikely - but possible), but B), it doesn't get any worse past 80mph, in fact, it almost feels smoother once I get to 90-100.
Any ideas? Obviously I could take it into the dealer to have them look at it, but first, I thought I'd check here to see if you guys had any idea.
