I posted this on my own thread but will see if I get a responce here:


Ran the Dart on Sun. 360 ci 727 4.30 28x11.5 33080lbs
60's were in the 1.55 1.54. This is with an Et of 10.93 10.92.

.810 T-bars Koni spa-1's full loose Car is set with a slight rake.

SS springs all factory clamps ,Rancho RS9000 set at 6, pinion snubber

When we added 4 spring clamps to the front and back portion of the smallest leaf and removed the snubber the car went 1.51. The launch looked a lot smoother.

Should the rear spring clamps be on the smallest leaf or the next leaf up?
