That's pretty close to what I'm planning on. My setup is going to use as much out of the box parts as possible. And thanks for the pic, Tarheel. It'll help me.

I did this style suspension on a short track dirt car.  It is fairly straightforward.  Here is a picture of the assembly, it is missing the shocks and the panhard bar. " target="">

I build models because I can't afford the real thing!

It's going to be more of a street machine/autocross style. The rear suspension I'm thinking of is similar to David Freiburger's Super Bee. I have the Hot Rod issue that showcased the buildup. It'll help me figure this out a little more. Thanks to you and aussiemuscle for the advice.

Quarter elliptics is an interesting choice for a Charger, but that's one of the great things about model building. Is this going to be a drag car in the gasser fashion?

Short of building a couple of Revell and AMT gasser kits when I was younger, I haven't built a quarter elliptical suspension. It would be a great fabrication project to use brass or plastic. There are lots of photos on google images to assist with design. This is probably not much help, but the set-ups are pretty basic from an engineering standpoint. Study photos to make your basic design, perhaps make a sketch, then head to your local hobby shop (or shop online) for some Evergreen plastic stock in usable shapes, and have at it.

Perfection is achieved not when there is nothing more to add, but when there is nothing left to take away.

Quarter-elliptical spring suspension
Posted by The Firefighting Modeler on Thursday, August 29, 2019 6:47 PM

I'm building a 1970 Charger with a custom suspension. I want to do a quarter-elliptical setup for the rear suspension. There's probably one for the aftermarket but I want to try to fab/bash one on my own first. I'm going to use the kit springs and I'll either use traction bars from AMT's 57 Chevy or NASCAR-style trailing arms. I don't know if I should install the shocks. Has anyone else tried this before? And if so, how did you do it?
