Hahaha. Funny but very sensible take, balong sir. I was wondering the same. The kit has long been tested for airflow & temps. Had logs of coolant & Intake Air Temps of it on & off thru my OBD hooked gauge & they showed no noticeable differences in any of the possible drive (spirited, static, twisties, straights) & weather conditions. These were concerns I personally had, so I dug.

On bumper damage possibly from the kit? I believe I would be the 1st to be informed of such should there have been any. I'm grateful not to have heard of 1 & I pray to hopefully not.

Hot Hatch even shared w/ us the opposite....about how the relocator saved his plate upon coming off an abnormally steep ramp that hurts bumpers. The purpose of the backplate that the kit comes w/ is to protect that wimpy, flimsy LTO plate from such unfriendly bumps.
Against floods? I'd worry more about the car than any other part should 1 decide to brave em.

...I seriously won't test the car for its amphibious abilities...I'm fine not knowing. Haha:D
Who knows, grover's may just have been a case of the service manager having a bad day, an upset stomach, or whatever else beyond logic we can suspect.
