I have a d40 Navara with 2" lift and wouldn't consider a body lift due to engineering difficulties and allighnment issues
but i do run 33" with rock sliders and dont have to many issues with cle......
I believe d40's can take 33s with less effort than the d22. I currently took my mud Flaps off since I got new aggressive tyres as they were touching in full lock although probably I should trim them like you did and put them back on.
If your able to post a picture, it'd be awesome as I need to do similar on mine.
Yeah engineering it is a pain talked to various engineers and one of them agreed to certify it.. But that's why I'm asking around before I start the process
