Torsion bars for better handling; your experience?
The Hellwig bars are awesome! I run the big one up front and the adjustable one out back in my '64 dart. Combined with all the other suspension mods and good rubber, it handles great! My only complaint is that it's under-sprung. I shouldve went with bigger Tbars and 6leafs in the back instead of the 5leafs.
Currently, my real hold up in fast driving is me boiling the brake fluid, and the non aggressive brake pad compound!
Oh yeah, and the fact that the OEM replacement clutch couldn't handle my mild 360.
Basically, what I've learned, is to upgrade at least one step beyond what you think you'll need. Otherwise you'll be doing it again.
