E92 under tray fitment

[amtasumf]

I am trying to find out the way to fit a new under tray to a 2013 325i E92 with M-Sport body kit. Third owner. The front bumper was damaged when it caught on a low sharp wheel stop in a parking area. Nearly pulley the bumper off.
The new under tray comes in 2 parts, the large tray and a wedge shaped spacer on the front edge. This however does not seem to hold the lower edge of the bumper skirt properly and allows a lip which will catch on any low curb. Photo attached. I am starting to think something is missing but without another car to compare I am guessing. The parts diagram is cryptic and shows a number of parts, some of which fit the M-Sport.
If any proud owner of another E92 M-Sport has some photos or help it would be appreciated.

I have a 335is which is E92 M sport bumper and yeah that wedge shape is part of the M sport undertray like that. Ironically I removed that wedge piece on my other car when I installed a big intercooler or else I would be to low to the ground with the front bumper.

Your images looks like mine.

dont reverse over curbs

Wasn’t actually a curb but one of the wheel stops in a parking area. Some have sharper edges and the 325i being so low it can catch the bumper. Having an obvious hook under the front isn’t a good design option.

I just don't go over parking stops but I have a front lip. But even before I had it, I just avoided driving over it in case I scrape. I decided long ago I rather look odd parking than mess up any part of the car while parking.
