Default Suspension for fast ride on rough and bumpy road

HI
Please help. I need to upgrade my suspension again. Now i have OME 2 inch, 35 inch tires, JKS set of adj arms, adj track bars, speed bumps and i STILL FILL EVERY BUMP.
I know the best option is to go with EVO, but is too expensive for me, for EU country with VAT and duty is around 17 k ( YES , 17!)
I know i will do it one day, but not this year, too many problems...
ANyway, what do U suggest for that set, i know i need to correct springs, shocks, need some steering correction, but is this worth, or I should now buy some long arm lift kit and all stuff what i have now deinstall and throw away?
WHat to do?

I thought that AEV may help, but as far as i know it helps on road, but not on gravels, county roads.
This year i plan to go to Georgia ( not US state ex russian terytory) , so it will be a lot of cross country travel with speed like 60-80 mph.

Please help as im spending money for last 2 years as a blind without too much of improvment.

So , If long arm system, then what is the best on that kind of roads? Flex is not so important for me, the most important to me is how fast and smooth i can go on country roads. From the other end- what LA shell i buy to get as close as possible performance to independent suspension systems ( is not possible but i know i can go very close to it)?

What about the Teraflex long arm with their speed bumps? You can keep your OME springs.

First things first. What tires are you running and what pressure are you running them at?

Lowering tire pressure is probably the most effective and cost effective thing that you can do. How fast are you driving on these roads? That may dictate how low of tire pressure you can safely run.

HI
35' tires, all terrain Mickey Thomson on Black MT wheels, it works very good.
I drive fast like 45-70 mph,depends of the road, but when u traveling long distance u need to go faster then on trial. Tire presure is just fine now, i have been experimenting with that for last 2 years.
Long Arme terraflex with their new advertised speed system may help.
The problem with JK as of any rear axel 4 links car is that trackbar moves the axel not only up and down , but also on the right/left direction when u hit the bump by one side. After that car rotates around own frame, rear just change the traction line compare to the front. It gives a lot of stress to the car frame, and gives a lot of unplesent vibrations. This is why EVO made their own system that keeps the axel tide on the bumps but still keeping a lot of flex when needed ( as far as i understand, never seen one on Europe )
So i was also thiking about Full traction system , they have developed something new, but i have read a lot of bad reviews about that companie's product, so i do not know what to do.
Other problem with JK was a lot of stress and noise when axel hits bump stops, but i have solved that by terraflex speed bumps. It works.
Now looks like i need to stabilize rear axel in up/down movment and reduce rigt/left movment, and find good spring ratio together with tuned shocks.
Looks like my optios are:

1) Terraflex long arm suspension
2) AEV suspension , but insteed of brackets i would use JKS adj arms, rear an front, up and down. Also i may use springs relocation brackets to keep them on place when lifted over 3 inch.
3) I may use just only rear system from Full Traction, and then use some short arm suspension from other company.
4) I may buy only kings shocks from EVO+ plush ride springs+ flip tie rod system from EVO+ longer pitman arm and new drive shafts ( plush springs have 4 inch lift so it will be needed, they claim their are smooth, i thrust them a lot so i may think it works, again, never seen them in live)

Help guys to choose. Think about that project as a expedition/ racing car not trial car. I have light bumper on front, i have small winch in front just to use when it will be needed. I travel with minimum of equipment to keep the waight down .

Hello and welcome, there is an EVO system in Europe, it's on my JK, and yes you would be surprised how fast you can go over bumpy ground, you don't get that front end launch you would get with most springs. It's the king shocks and springs that are doing the work, and the gas bump stops.
I had the Aev full system on to start with, and it was good, miles better than stock, but the EVO system is on another planet, the flex is mental, worth every penny.
If you want to see my JK, I am in Devon.

What OME system r u using and how much added weight do you have on your rig? There are several OME options (Light, med or heavy duty). I have the HD kit and Its bumpy as hell on all off road situations because my rig is currently too light for them. The HD kit is designed for winch and aftermarket bumpers at minimum.

I use AEV drop brackets with both upper and lower adjustable arms just so I can go fast and brake hard. The brackets are inexpensive.

X2 on air pressure. I run about 28-30 lbs. if I go higher the ride starts getting rough. Any suspension will be rough if your running to high a pressure.
