My car is a 78 with full interior. I have the plates to stiffen up the sway bar area from bad dog welded to the chassis. I have done 2 track days and an autox so far this year, and the few pictures I've seen of my car in the turns, and what it feels like from inside the car, shows I am getting a ton of body roll. I have the stock bar up front and no rear bar. I have konis all around with 300 springs in front and 250 rear. I was looking at upping the front bar to help with the body lean, but not sure whether to go with 1 inch Addco or 1 1/8 inch st front bar. There's a chart in the black dragon catalog that shows the percentage of how stiff each bar is over stock and shows the 1 1/8 bar to be a lot stiffer than the 1". I don't want to go too big and have the car act more like a solid front axle. I'm not even sure with these bars if that's even an issue. Is one size recommended over the other, or is bigger better? I've read in the suspension faq and it seems a lot of people use the 1", but those are on much lighter cars than mine. What would be the better choice for a heavyweight 280?
