Well the faster Dart will 60' in the low 1.20's at any track I run at around here on Caltracs. Easy to adjust and I can run a stock susp. class. I can put either of my Darts back on the street with little work and have a good ride. Never an issue with traction at our local tracks so i just do not see a need for ladder bars. I still think of my cars as not being all out race cars as they do have a stock style suspension in them.
