Hello @Rawadand all other subscribers to this thread, thank you for making me aware of the discussion, it helps a great deal to understand what type of mods are to be considered for the Y62.
Bearing in mind that I am just starting my mods, I went as far as I am concerned to the essential. Having said that, I hate the original bumpers with a passion, I can see that it can become a money pit. I have checked into the mods you have undertaken on your car and as you indicated but the 2020 model is still under development.
As for my car, I had installed King Front and back coilover shocks with adjuster, I changed the rear springs, a galvanized skid plate, a ARB onboard twin compressor, 18x9 XD alloy wheels (I considered installing 17" but I would have had to modify the calipers), the tires are BF Goodrich all terrain 285 X 60 X R18. I also fitted other mods but this is for my own comfort and has nothing to do with off road driving.
So the big concern are these bumpers which I need to modify without waving the warranty. Any tip is welcome. See you all on the road.
