Much more air in those tires. M/T tire guy told me if they spin, put more air in them. He told me not to exceed 26 psi. You are not even close to where you should be with air pressure.

I would certainly try 1/4 pound of air in tires, see what she does- cant tell from pick where you are in relation to leaving on the light.
secondly- what front brakes do you have on the car?
If its the factory disc brake set up- you can easily lose some weight up front by going to aftermarket race brakes.
Not sure what your torsion bar options are for that car.
Yes, a little tuning on them can make a big difference, but you absolutely NEED scales.
Surely someone over there has a set of scales.
are you running a front anti-sway bar? If so, i would likely pull it off , save some weight, help front end respond better.
Do you have a picture of car just sitting still with 572 installed- a pit pic, from the side ?

Get the tires up to about 13 psi and try again. Keep adding air from there.
Next suggestion is some double adjustable front shocks.
Strongly suggest progressing the nitrous.

Put Your car on scales and let's see what the weight distribution is now with the new motor. With weight/load numbers You can decide the 'how much?' and 'where?' questions if necessary. Also, is this a torsion bar frontend car or coilovers/Struts/...???? no possible weight 4 corner in italy... Sorry.. i know only total weight 3650 LB There should be many road course racers in Italy. They will have 4 corner scales. Make friends with one of them.
In theory, there is no difference between theory and practice. In practice, there is.

Set the CalTracs in the bottom hole (First).
Set the shocks on a pretty tight compression (Meaning hard to compress(1-10 set them at 8) rebound about in the middle (Second).
With you in the car and the bars set neutral put one or two flats of preload in the CalTrac bars (Three).
Set the tire pressure around 10 PSI (Four).
Report Back (Five). Very good Infos ..Thanks for your Help .. therefore is better at 10 psi ? my tires is 29.5 /11.50/ 15 drag MT .. yes Calvert bar was adjusted at 1/4 preload with my ass .. 10lbs-12lbs of tire pressure will help the car not slam the tire in the ground. The lower hole will help not hit the tire so hard (more push than bang) better lever. Good luck and let us know how it goes

i Think .. when my car will wheeling like your Duster ... my 60 FT will be ok ! Don't forget that your back may end up hurting from the new hard leaving  I've had to learn that lesson more than once,  Make sure and push yourself back into the driver seat before hitting it real hard

New look is Super!!! The only thing I would add at this point is to only make 1 change at a time. Don't change air pressure, Caltrac setting and timing at the same time. You will never be able to determine what made better or worse times with too many changes.

Loosen the rear shock extension 1>2 clicks at a time so it stays on the tyre after the hit.
