Quite ideal for me. Been lifting and storing all my cars going back 40+ years never had any issues. Before battery tenders I'd pull the battery and keep it on a low charge in the house in a cool dark place (basement) with the battery sitting on a piece of wood (not concrete).Far from ideal. Get the wheels back on it, and keep the suspension loaded.
"or else"
I don't keep the wheels on as I don't want the extra weight on the suspension while it's lifted and on the ZR1 I was worried about the mag shocks as I have read stuff about not keeping them fully extended but according to my Q&A with Jim Mero shortly after getting this car there was no issue according to him so that's what I do otherwise I would load up the suspension with stands while on the QJ.
