Yep, I had 1.06" T-bars on my Dart and tried Autocrossing and Road Racing and there was definitely a lot of leaning where I was machining tires. That's with my sway bars and shocks set to full-stiff. I'll be adding helper springs to the back of my Dart too.

As for T-bars, Hotchkis stopped making them so unless someone has them in stock, new ones aren't being made. I'd go for Firm Feel T-bars. With your shocks, you have enough damping for the larger T-bars.
