Car shaking when idle after cam installation
I have a 2011 grand sport.
I had a custom camshaft installed with a .660 lift. When idle the car shakes inside.
Is there anything I can do to stabilize the inside of the car, so when im at the light my wife isn't getting annoyed at the vibration?

After you installed the custom cam, did you have the engine dyno'ed and computer tuned to take advantage of the new cam's characteristics? If your cam is too radical for the stock tune, that may be the reason you have such a rough idle.

True, to compensate I can rev the gas a little and it calms down. I had a tune after the cam install.

have the tuner raise the idle some
Does the engine visibly shake bad itself ot youre just feeling a gentle rock to the car, tell her to quit whining
A rowdy cam, youre gonna feel something inside.
Which cam is it?

more importantly, what is your lobe seperation? LSA and duration are the main factors that determine how "lumpy" your idle is going to be. I bet you're probably somewhere around a 110-112 LSA. My cam is a 114 and isn't super choppy but still rocks a little at idle. You can't do anything about the car rocking. Your wife is just going to have to get used to it, or quit riding in the corvette. I think the car would sound crappy with a bumped up idle.
