Gen4 leaning after lift kit install - what to look for?

I have a gen4 LHD Jimny that has a leaning after a lift kit was installed.   The kit is a 50mm lift from iron man (front and rear springs, front and rear sock absorbers) which came with the parts they mark for the RHD Jimny.   
Before the lift kit I got 225/75 r15 AT tires installed on the stock wheels, I did not noticed any difference on ride quality, but very little power loss.
Then I got the lift kit installed and the ride became rough, uncomfortable and bouncy, as well as leaning to the passenger side which activated my OCD.
I did some research on my issue and was thinking that as I have RHD parts installed on an LHD this was the culprit, but the supplier confirmed that I had the correct parts for the Jimny sold in this part of the world, I still have doubts on this. 
The rear springs have different sizes and the one marked as driver side, the taller one was installed on the driver side of my LHD gen4. 
A quick measure with my hand shows that on the rear driver side the gap between the tire and the flare is bigger.  

Is there any tips/recommendations on what to look for or maybe what can be adjusted?
Should I kit the car with more weight as the springs are rated for 0 to 200Kg?
 
I don’t have experience with Jimny nor lift kits but I have been eyeballing some replacement springs and to keep the shock absorbers. 
I contacted Jimny style and asked for the H&R +40mm springs LHD which I was told should fix the lean but that the rough ride is also tied to shock absorbers and I am confused on what is the best option for me as I just want the lift mostly for the looks at the moment.   

From what I can find it seems that all Australian off road suspension is designed on the supposition that the vehicle is going to be significantly heavier than standard and so is going to require hugely stiff dampers to control the weight. None of them that I can find offer a taller and softer more compliant ride that you might want in an off road vehicle you don't intend to live in for months at a time. With the car unloaded how much lean are you finding and if you add a driver does it improve or get worse?

The lean is noticeable by looking at the car.
Is measuring the top of the tires against the flares a correct method to get data about this?.

When I drive the lean improves a little bit i would say but i have not asked someone else to sit so I can take a look outside. When driving I can feel the lean to some extend and depending on the road it gets more noticeable or not.

And yes I don’t want to live in the car

History of "the lean".   The lean affects Gen3 RHD Jimnys. On these Jimnys Suzuki fitted different rear springs to each side. On the LHD the rear springs were the same each side.  This therefore created the need for aftermarket lift kits to compensate in the same way either through correctly designed rear springs or simply fitting a slightly longer spring to the drivers front spring.

Despite Suzuki slightly altering the suspension on the Gen4 Jimny, the same situation still exists, RHD Jimnys have different springs on the rear side to compensate and LHD dont. 

Therefore, as you have a LHD Jimny, if you fit a lift kit designed for a LHD car it should be fine.  But if you fit a LHD kit to a RHD car or vice versa you will get a slight lean.  You will find that most providers dont bother with any correction at all so most kits are effectively "LHD" versions.

Martin, which way does a Gen 3 lean? I only ask as I think mine leans slightly to the passenger side. I have heard that the drivers side sags eventually with the weight of the driver, so perhaps the previous owner changed the drivers side spring.

I am not sure if I am sensitive to a lean, my other car seems perfectly flat, but of course that might lean slightly to the right?

The Old Man Emu lift kit come with different length rear springs for the Gen4.
