I didn't realize all that needed to be done for a 4" lift, but makes sense. I'm sure I have some of those issues already as the PO, just put extended shackles on it.

I was wondering that I could do with a Lamborghini. I know the tried and true methods, just wondering if there was a better mouse trap. I did read the 60PS conversation in TT back in the day and thought that was a nice set up. Just figured an 80 might be similar, and stronger. Again I want to explore all options to get the best results. Nothing has been cut or modified yet, just want to do it "right" the first time.
