Front segment goes solid when caltracs bar rotates. Your shocks control how much it separates. I think you need better rear shocks. I would say normally you would be right but this pic if you look closely the rear end has less than a half inch separation..the wheelie bars rotated down 9 inches plus.... and you can see the back of the leaf spring twisted out of the bottom of the car... this is not a progressive setup I'm trying to hit it with all the horsepower at the hit..I was told..that this is a common problem for A body Mopar the long rear segment .. we tried to put a GoPro. Down there but it snapped the bracket at lanch ...also I run two inches of lowering block. Which is probably helping to leverage the spring

You might try 1" block instead of 2"...

But it is still rotating your housing causing your shock to separate. Where and how are your rear shocks mounted.

The shocks have been relocated they're straight up and down

Are you full tight on your extension?

I have been running 2 or 3 on extension and 10 or 12 on compression.. if I go too aggressive an extension the car will not plant the tire.. the car will not even move 3 inches before blowing the tire off

What hole on caltrac do you use? Why so loose on compression? What does it do if that's tighter?

Leafs in lower hole .and caltracs bars in Lower hole.. if I tighten extension past 5 with these shocks the car will not move forward it will instantly blow the tire off

I would try going to your upper hole and tighter on the extension and compression. All adjustments on shocks are made from full tight, so if I were to say 6 and 12 they would be clicks from for tight. Brett's are going to be run at 2/4 when he brings out the new motor.

You watch a Rod Rhoads pass on you tube,you will see how little his rear moves on launch.

Ron Rhoads front segment is much longer and probably set as low as possible.
Despite all the guys saying springs just hold a car up, a stiffer spring will increase leverage and might be just what you need to do. But, with you not being able to set rebound stiffer, it might create another problem

Couple things...........if you have lowering blocks now, you either have the wrong spring, or them mounted wrong. If the car sits too high without blocks, do something else, because blocks are BAD. Two, a stiffer rear segment won't do dick to solve your problem. The bars are welded to the housing. If they rotate and hit, it's because the front segment is letting the housing wind up. The front segment is too flimsy and or bars are not adjusted right. The purpose of a cal-track or similar device is to stiffen the front segment. The rear segment does NOTHING, but hold the car up.
We have a Nova we run that doesn't even have a rear segment. We use the front half of the spring only, with coilovers. I have it so stiff, it's like a mini ladder bar

Ron Rhoads front segment is much longer and probably set as low as possible. It would be 24" or 25" (S10) as apposed to 20" for A Body Mopars I'm not an expert, but I'd say your shocks aren't valved correctly.

Someone mentioned Ron Roads so I figured I'd post a picture of the bottom of his car I believe this device is used for controlling rotation Maybe but I'm not a hundred percent sure

Also this is an image of a heavier leaf spring. If you notice it's about an inch thick I'll keep you guys informed on how this works.for me

He also has a anti-roll bar to control body roll. And Smith bars instead of caltracks. Not real sure why the wishbone with leafs but it certainly would not hurt.
