Im not worried about the back being weighed down, because I hardly have anyone with me. I’d just need to get a set of softer springs that would make it level with no weight in the rear. Or, if it is cheap enough, wouldn’t mind getting it converted back. Im just very particular about parts they’d use and if it’ll be as good as factory.something to consider as well, since their is no ride height adjustment for the back those springs will have to level out when you are full of passengers. With the back running a little higher it will shift weight to the front as well. I would throw tape on another car of your type and see what the front measures. If yours is close I would drop the back and just let her ride low on full load or get some after market air shocks that you can bump up a bit for a long drive with a full load. I think the front is probably fine and the back looks up a couple inches higher than normal (from the picture anyhow) and appears to be dipping the front a bit due to this. There is my 2 cents~!
