Your vision is nice, but unless you are hitting the drag strip it's a bit overdone. Without any flex you might as well have just bought a Camaro or Firebird instead. Let's not forget they were made the same years as g-body cars and sold in similar numbers some years. If you overdo your suspension, you will feel like you screwed up and end up just taking some of those parts off and putting them on here / ebay for sale. I'd suggest removing a few items from your list and saving the money ahead of time. Eliminating frame flex is ok, but annihilating it entirely is poor judgement, especially if you live in a climate with ice in which case your 'dream suspension' with 0 flex will cause you to spin 3 times and smack into a tree the first time you drive in a snow storm... come on man
