20s for the Demon - how low can I go? (big wheel haters don't look)

Sounds like you need to put the front where it's gonna be and work off that. Good luck it is coming along nicely. Two thumbs up here!

Makes sense and thanks. I guess I'm hoping someone will be able to say something like, better keep the K member at X inches off the ground to avoid header problems. Or, the front suspension will be on the bump stops with the K member around X inches off the ground, and it should be raised about X inches above that for reasonable front suspension travel.

I do have a Dart Sport parts car with suspension intact but no engine. I could put some weight up front and take some measurements. Input about headers and front travel would still be needed. I understand TTIs tuck higher but I won't be buying them.

how did you get that bolt pattern?
The car is a bare shell sitting on a rotisserie with no diff. The wheel is just for mock up.

that looks too "Oakland, Ca" for me...
I think I'd have said the same thing until a few days ago. My daughter thinks its rad. The front frame of this car is off a Duster she wrecked. After seeing this wheel on, she wants another one. I'm from another place that starts with C - Canada, way up there on the Alaska highway. Never saw anything that looked like this up there.

About coil overs, my first thought was the overload type shocks. Shows how little I know. I was not planning to convert the rear suspension to coil over type. As long as a leaf suspension does not require more than about 4" travel I think I can build the tubs with enough clearance. Perhaps I should add a leaf or get stiffer springs. It would be nice to keep the factory trunk lid spring. I think I can keep it and provide about 3" of tire clearance. I'm searching for leaf spring travel info but so far not finding it.
