http://www.youtube.com/watch?v=SNR4ELAoM6oSo Based on the little bit you can see of the leave what do I need to focus on now? basic rundown is, SS springs 2800lb solid eye bushings, /6 T bars,MP rear shocks, Calvert fronts, stock A arms and front susp. SS springs are clamped on every leaf (testing showed improvement) This car hooks but the 60' seems slow to me. You'll notice I gave up the win light (and a lil dough) but what's the first thing that comes to mind that you see needs a change? Thanks guys

The front lifts but the rear doesnt do anything... first would be rear shocks... get some adjustable ones and the rear tire pressure looks high

I would definitely agree on tire pressure, freezing cold night and I was worried about the car moving around up top so for stability I kept pressure in it to avoid pedaling. What's your take on the rancho/calvert adjustable rear shocks? Thanks much

The Rancho 9 way would be the MINIMUM... alot of guys use them with the Caltrac but they are IFFY with SS springs... but from your vid I would say to try them... you lacked any lift in the rear that you should get from SS springs... what gear are you running

If you go to the roundy round section of an AFCO catalog there is a lot of info on rear shackles and the effect of different setups. Well worth reading. If you have no rear lift, I suspect you have too stiff of a set of SS springs, poor shackle setup, bind, or some or all of the above. Too stiff on the shocks could be a culprit, although with SS springs that is very hard to achieve due to their very high leverage. The only other thing I could think of is spin at the hit(I didn't watch the vid, so,,,,) I put a set of 002 and 003 springs on a 3300 lb Dart I am building and used stock shackles. It is stiff as all get out back there now. Not what I wanted. I should have bought the ones for a 2800 lb car instead. It is much better to have a low spring rate and control it with shocks and clamps than too stiff a spring, which can't be fixed without replacing them.

I think in the spring I'll try and remove some of the clamps on the rear segment of the springs. I actually tried 002/003 springs this year but it would knock the tires right off on the prepped street. The 2800lb springs will pick the fronts on a decent concrete street after a proper burnout.
My ss springs were always best with rear segments unclamped. Long drag shocks and or shock extensions. just a clamp 6" behind axle let them fan out on launch.
with the cal tracs SS springs and 9 way adjustable was best with rear of springs unclamped and shocks at 7 for foot braking.
