My Demons front end is very stiff. Pushing down or pulling up on the car yields very little movement.
It has 888-9 torsion bars, /6, Koni adjustable that are set to the loosest setting, and the front end components are all new. Not poly, just the standard bushings.
I compaired the Koni's to the Doetsch Tech 3 way adjustable (Summit Racing) and the Koni's are much looser.
The torsion bars are not cranked up all the way. When I got the car they were. It had a 340 in it. and when I set my all steel 440 in , it barely moved. I dropped the adjustment so that it would have more upward suspension travel for launch.
It has no bump stops for the upper control arms. And the suspension does move when it is jacked up. but takes a bit for it to sit down after it has been in the air.

What should I look for/ what do you think would be causing the stiffness?​
