Best shock absorbers without lowering the car

[nazab]

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 ...

Konis are an excellent choice, highly adjustable for tuning. Bilsteins are original equipment on SRT8 front, also excellent.

I also like KYB. But I am not aware if they fit your car or not. Note that many LX have Nivomat rear shocks that give load leveling capability.

Purchase with a credit card that protects you and you can send them back if they don't work. You may have to pay for shipping in some cases.

We offer our GSR line of shocks for your car, they would most definitely improve the ride and handling. The GSR uses a technology that will auto adjust to the conditions, so the highways will be comfortable, but when you start pushing your car they will tighten up and perform

Sway bars will remove the float and stiffen the ride up while improving cornering with less sway. I think its a better option than shocks.

[Rob@WretchedMS]

I completely disagree.

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.

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 .

Where do you live?

The main reason that i mentioned springs, is that our springs are a bit stiffer, and are matched with our shocks. Replacing the shocks and springs (even with 0 drop springs) would help the highway ride, and cornering, bushings and sway bars would be something to do after that, but not before.

[nazab]

I live in Egypt ... Are there 0 drop springs ? First time to know ... so these are of the same height of the original but with a higher rating ? On all the products I found on the web regarding springs, they are always lowering springs ...

[Rob@WretchedMS]

for a 300C it looks like our 0 drop springs would lower about 5mm-10mm

Front #7941
Rear #2981

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)

Discovered today heavy duty shock absorbers by Bilstein replacing the OE shocks of Sachs and goes with the original springs and setup .. has anyone tried these ? are they better than KW shock absorbers ? Koni ??
