Mulfab advertise a centralising block of 3/8 inch, which will move axle back by 15mm and also a lowering block at 19mm, which will also lower it by 19mm. I think the first step Vassilis would be to have a look at your axle to see if there are any existing blocks between the top leaf of the spring and the axle. Whilst there, count how many leaves are on your current springs to determine whether a change from standard has already been made.
That explains it, I have these lowering blocks on my 4/4 which I believe was a standard fit at the factory from approx 2012 onwards ? Dave W would know.
You can just see them here if you zoom in
