So my best friend brought to my attention that the U.S. Car Tools subframe connectors require welding to the floorpans (which I knew, but wasn't thinking about). Before I began to see my car in the reference of trying to make less "invasive" performance modifications, I was all set to use the U.S. Car Tools frame connectors.... My Assassin traction bars are shipping next week, and I'm ordering my Calvert split mono leaf springs and sliders as well. So while the car is having the front and rear suspension system replaced, I may as well tie the front and rear frames together. What brand of subframe connectors do the best job without having to weld them to the floorpans, and how drastic of a compromise is that vs the U.S. Car Tools pieces and technique? Thanks to all of you. I want to make the order by next week, so please let me know what you think!
