Put the bars in the lower hole on the front mount if they aren't already. Start w/ 1/4 turn preload on both sides and tighten up the shocks.

The pinion angle is a combine driveshaft/pinion at 4' . The car had ss springs before and 60 harder with those , Yes centering pins are in place and correct! The rear was in the car since stock springs which happens to be a moser 60 . we are trying to make these work,! As for calling them that to has been done on several occaisions, thus we are at this point a, post here to see if any out here has had the same type issue ! I really thought that a post here would have come with advise as to where to look, ? must have been mistaken !
Whats your front suspension like?
Something is obviously wrong somewhere as Cal tracs are a proven system. If you don't get your panties in a bunch real quick(see quote above) there is lots of great knowledge on here.
Thank you, frustration kicking in ! The front has been looked at to the point of removing shocks, checking for any tightness /binding in any part of travel. new 90/10 installed , rotors pads calipers removed replaced ! front shocks reset to easy out hard in ! new rubber pads put on lower, upper are the poly type that hit and been cut down for @ 6-7 inch travel . The car goes straight as a string on leave everytime , the issue is in the 'bunny hop' I have the option of putting the ss springs back on but the car will twist pull the left front while leaving the right on the pavement

How wide is your rear rim? Are the tires stiff sidewall? tubes? Air pressure? Just from what I'm reading, it sounds like the tires are getting hit hard and they're too soft. You have a heavy car that seems to make good power...what kind of power is it making? Just sounds like it needs a stiffer/more stable tire.

12 rim new dot hoosiers, quick time pro, 30,13,15, we had reg hoosier slicks 29.5 10.5 tire was told to try these . air pressure has been from 18-10, the car does best at 15 ! it has been on a chassie dyno, and paid a guy 1200 to do what he called a super tune lol, the car ran 3 tenths slower, he said it produced 485 hp at the rear lol! And the setting almost put me in the wall drove hard right out of the gate. I want to think that i am just over looking something easy simple here , just need a liitle guidance

Make sure rear shocks have 1.5 - 2" of extended travel with rear springs fully unloaded. Use lower hole in bar adjustment. Add preload to the bars with driver or equiv. weight in seat. (I have 1/2 turn on left and 2 full turns on the right). Rear shocks worked best for me at #7 setting with the Ranchos. Verify rear spring hangers are pointing rearward and move easily. I ended up going with AFCO double adjustable rear shocks for better results. Best 60' so far 1.33 on a well prepped track. Avg: 1.38...took lots of time and passes to get it consistant.

I had the same issue as you when I had chassis engineering 3ways on the front. calvert 90/10's and a loose front does wonders. also, I was told QTP's like softer settings. 7 seemed to work well for me, but next time out I will try 5 and under. i'v also found if your making under 600hp the bar may work better in upper hole. john calvert told me bar should be as level as possible. thought i'd just see for myself. put it in the top hole and went from 1.46-.49 to a 1.45-.47 so just try it and see what ya get. my car is an A body@3300#, so that may make a difference on the settings compared to mine.

Well your car is very close to the same as ours. I have them in the top hole. .060 gap on driver side and just touching on pass side. 9 ways on the rear also. have them on 7 right now. and have caverts 90/10 on the front. only shock I could get to work. Makes me wonder if your rear shocks are bottoming out or extending so far ?
as it sits now the bars are in the mid hole with 0 degree in the bars but a 4 deg in the rear , the right bar has 1/2 turn pre load , while the drivers side ,( wiegth added for driver), is just touching. the rear shocks are set in tightest setting. they are not bottoming out ! Rear tires have been run at 10-18 psi still does the bunny hop, could more air be better?

Wow, that's going to take a while to read.
It's worth the read.
And a set of the D/A's if your making any kind of power with caltracs is the way to go...Couldn't get them adjusted on my car at first, but now I have no regrets with the money I spent there
