Mopar suspension input needed

[Rolling_Thunder]

Well... I am looking to make my Charger handle a little better... looking for some input......

The plan is as follows:
1.00" torsion bars
1.25" frant sway bar
7/8" rear swap bar
welded subframe connectors
boxed lower control arms
tubular upper control arms
XHD leaf springs
misc stregnthening of K-frame

All good choices. I have almost the exact same setup, but I went with 1.120" t-bars. You might consider Koni adjustable shocks also.

[Rolling_Thunder]

eh... 1.120" seem to be a little too much for the street arent they ?

[PeteRR]

Nah. I love the ride. Of course I'm also running a modern cushioned bucket seat in the car from a '99 Chrysler 300M.

I am running 1.120 t-bars also and actually think they are a little soft. The XHD rear springs are soft also, I am thinking of finding something stiffer in the future. Iron headed 440 in 70 B-body.

Mopars tend to be undersprung up front by a substantial amount. If your planning on a 7/8" rear sway bar, you maybe putting more rear roll couple into the car and cause it to push. You could drop the rear to a 3/4" to bring it back inline, or step up the ront torsion bars a step or two to get it more neuteral.

[Rolling_Thunder]

hmmmm sounds like a plan.... so bigger T-bars, smaller rear sway bar, XHD leafs and some stregnthening on the K frame ?

[Blaster11]

You might want to give these guys a call and talk about rear springs because if you want it to handle the XHD springs are pretty soft.

I'll disagree with that to an extent. If you look at the oval track kits mopar developed back in the day, they only used 120# leaf springs. The XHD units are in the neighborhood of 150# with some of the superstock springs going up to around 180#. Certainly not a lot of wheel rate there. If you want to look at a modern comparison, there is a lot of oval track and road race cars out there that are going with softer spring rates and higher sway bar rates so they can still achieve the same roll couple, higher roll resistence, and softer jounce and rebound, which is easier on the tires.

I still say go big up front and stick with the XHD leafs and use rear sway bar sizes to tune the handling to your liking.

got it... somewhere i read an article... 67 Coronet with a 440... .96" torsion bars, tubular upper control arms, frame connectors, poly bushings, XHD leafs, 15" wheels and tires.... pulled a .92g i'll see if i can dig it up...

The Green brick is also a good example of mopar handeling potential....
