what point on the wheel does this chart refer to? It mentiones wheel diameter but nothing about tire size. The measurement appears to be fender lip to level ground I am assuming.

This is an older chart, but it will give you an idea, (note: 7941 is not listed as it wasn't available at the time)

We sell sway bars too, but i would not put sway bars in front of the shocks/springs on these cars. The sways will do little for straight line stiffness and stopping the porpoising that he complained about. Shocks will though
Yes the sways will help with the sway, but we've found that the sway bars are actually asked to do to much with the other weak points the suspension has. It's a bit like putting a bandaid on a stab wound.
Well, maybe that's the case with the Pedders sway bars, but it not my experience with the Hotchkis sway bars. They removed the float that the poster spoke about that he has, that I also noticed when hitting large bumps at highway speeds. They also stiffened up the ride...not a lot, like springs would, but it is firmer. They also made the car feel 500 lbs lighter when cornering even on stock rims and tires. They made a dramatic difference without taking away from the overall ride quality of the stock car...for very little coin.

I think the sway bars have to do more with the side movement of the car on curves and the body roll on curves , but the frequent up and down motion of the body over the large bumps in straight line motion will not be cured by sway bars . it is the role of the shocks . I don't know how far will changing the springs cure this problem either ! I know that most guys change the springs to lower their cars for the looks , but are shorter springs stiffer too in the sense of reducing this yoyo effect ? I don't want to lower the car as the roads here are full of bumps ... Your feedback would be a great help .
Well they actually tie everything together and do effect ride quality as they limit movement of the suspension. I remember a few years ago when SVT modded the Mustang suspension to the Cobra version they used larger sway bars than the GT model, but then went with softer springs. Without knowing your definition of frequent up and down motion, I can only say that the sway bars took out the float the car had at highway speeds hitting large bumps...not potholes. I would think a beefier shock and or spring would also help. Problem is everyone sometimes has a different definition of ride quality. To me the SRT is too stiff and the stock C a little soft, but the sway bars put ride, handling just right.
Maybe, I'll get a ride in a Pedder's car to compare one day.

the issue of jounce/rebound control using sway bars, when both left/right tires move as one, is really more ofa function of the tightness of the bars to the sway bars. the Hotchkiss bars to bushings are not that tight, and with the extremes in weather, may be subject to lots of noise concerns. Our sway bars have extremely stout sway bar bushings and would, to a small degree, and I gues the Hotchkiss would also, have a minor affect of that equal movement. but in terms of control and bang for your buck, a shock and spring assembly like our Pedders units, are a much better value to purpose than doing bars. Also, without a doubt, our Pedders springs/shock combo will gie you the highest quality ride of any of the performance shocks/springs that are out there.

You are right about the noise with the Hotchkis, which is why I remove them and installed the Police Bars. 9/10's the performance without noise as it uses OEM type bushings.
What I do like about the Peddler's product is it looks as the components were all designed to work together, which to me is the only way to really get good results. It's much harder trying to piece components together from various vendors.
However, to me the ride of the stock C is pretty much spot on, as it is after all a luxury car, it just has a little too much lean in corners and float on the highway at times. If my car was a Charger, I'd be wanting a firmer, more controlled ride for sure.

Ride quality is important. But the springs on the 300 are not strong enough. A 300 does have a serious amount of body role.
So what I would suggest is to find a LX that has a Pedders spring/strut/bump steer kit installed. I think you will be pleasantly surprised on the quality ride with the increased handling

So you mean changing shocks while keeping the original springs will not solve the problem as the original springs and shocks are too soft !! So which springs/shocks are available that are stiffer and will not lower the car ?
I have 300C 5.7L , don't like the soft ride and floaty up and down body movement over the large bumps in high speeds , but I don't want to lower the car .. so the right thing to do is I guess to change OE shocks by stiffer /more sporty ones. The choices I found from reading all the threads in the forum are the following :
1) Change the OE shocks by SRT8 OE shocks ... technicaly it is ok and makes sense .. but has anyone tried it ? does it really help ?
2) Change the OE shocks by KW sports dampers ( Not KW1 or KW2 ) , just sports dampers with the original car springs ... again has anyone tried this ?
3) Found Koni shock absorbers offered through only one vendor and not even mentioned in Koni's website or through any other supplier or source !! These are more expensive .. but I have worries to buy a product that even the producer denies that it produces it ! What will happen if doesn't actually fit the car or if anything goes wrong with any of these shocks ? what kind of warranty or guarantee would one expect ? Has anyone tried them with the original springs of the car ?
Your advise on any of the above would be highly appreciated guys ...
The Koni shocks that we carry is a Custom made unit that Koni has produced for us, for the LX Platform. They are carry the full Koni Warranty.
If your worried about the warranty aspect of it you can email Jim Ryan at Koni, His email address is Jim.Ryan3@itt.com
