Garage lifts and doing damage to suspension

[billschroeder5842]

I'm running out of space and need to consider adding a car lift in my garage. I have a buddy and he is very happy with his single post lift that positions on the pinch welds.

I have questions as to getting a lift that allows to the suspension to "dangle." Does the "dangling" do damage to the un spring suspension? The lift will alternate between the ZR1 and the '04 ZO6. I know there are other "drive on" lifts but the foot print and the awkward lifting has me hesitant

Any thoughts? Thanks!
