Hi @jose Shanu I dont think it is "needed" for newbie drives, but I got one fitted after my 3rd or 4th drive as at the same time, I wanted to get the skirt / body kit bits removed from the front bumper. I will try and attached some photos shortly of before and after the skirt removal. I would definitely recommend the bumper adjustment after your first couple of drives to avoid unplanned removal in the desert
being specific on the bash plate, It definitely removed concern about causing any additional damage, and with that boosted my confidence to apply the gas pedal approaching crests and as a result I think my driving in the desert improved!
