I don't know. Initially in 2010 the V6's rode high in the rear. Chevy fixed that by 2012.
If you want a noticeably lower ride, go aftermarket springs. But as I said before if you're looking for improved/flatter cornering, go with a nice inexpensive FE3 aftermarket sway bar set (BMR is a good way to go) and your vert will surprise you!
