Lower bumpstop travel

Boduke said

72 dart running 6cyl torsion bars with 318.. i have the ride height set at 1-3/4 between the lca and the fram. My rock auto bumpstop is 1-3/8. Leaving me 3/8” of travel.. i may have set the ride height low but i like it where it is. Question.. how much should i cut the rubber bumper ? Or how much space does most everyone run between top of rubber bumper to frame..set for grandma driving to church specs..
thanks

Good grief.

If you like the ride height where it's at, you have one choice to do this correctly - buy significantly larger torsion bars. You could also buy 2" drop spindles if you insist on keeping the inadequate torsion bars, but you'd just be trading one set of problems for another.

With /6 bars you will need every bit of that bump stop, because you will be constantly using it. Even at factory ride height you'd be using it, and you're much lower than that. Removing the bump stop to gain back travel is a terrible idea in this case, because you still won't have nearly enough travel to keep the LCA from bottoming out on the frame. Running without bump stops is never really a good idea, but with substantially less travel available than what the car will use with those torsion bars it's a really poor decision for this application.
