I don't see any subframe connectors mentioned in your mods. That needs to be #1 on your list of mods before you add any more ponies!

auto roc put a 6 pt roll bar in his car, which i would highly suggest. It will bring a lot of the flex out of the car. I am currently having my fabricator build me a 6 pt chromoly roll bar with swing out bars and a X brace. I think i should have my car back at the end of the month, but no promises.
