Little bit of an update as I seem to have accidentally highjacked the topic to be about the front bar mod and documenting its progress lol
I emailed the company a few days ago and they probably wont reply back to me seeing as I probably sounded like someone who wanted to get measurements from them to make another competitor product so I dont see any progress being made on that front. So the next best thing I did was to see if the measurements of the metal part shown a few posts ago on the cx-3 can accommodate the subaru rally bar. I dont have the exact measurement right now as I did this a few days ago but I checked it against the following dimensions.
-The 2015-2017 subaru wrx rally bar spacing of the 2 outer front mounting tabs are 21.75" apart as stated by the rep in an answer.[see source 1 question section]. Unfortunatly as life has taught me, nothing ever looks like it does in the pictures and seeing as that picture is shown exactly the same in multiple listings for different subarus I needed a real visualization of it. In [source 2] there is a installation video of someone installing this exact bar on a wrx and just a bit after 5:20 you can see a glimpse of the mounting tab of the light and its position to the rear mounting tab. The rear tab itself extends further than the front mounting holes used for the lights so the real dimension is going to be greater than 21.75".
I dont have the exact number of the dimension of the metal part of the cx-3 but 2 things are wrong here based on this information. The actual mounting hole itself that bolts onto the car is further than the dimension of that metal panel on the cx-3 so unfortunatly that position is not going to work. Also there is the issue of the giant width of the rear tabs and the clearance of the lower front grille of the cx-3. If you go up the picture showing the lower grille will also show those 2 vertical plastic parts which would get in the way of mounting the bar in this configuration.
Fortunatly not all is lost. After watching his installation videos and also installation videos of the second mounting type of this rally bar (vertical mounts on a crosstrek) I think we might be able to mount it onto the crash bar itself like the video actually shows, depending on the distances and dimensions. The mounting hardware/piece is going to come in handy by the looks of it and at most we may need to drill a hole to bolt a piece onto the crashbar and then attach the rally bar to it.
Again its most likely that the ideal rally bar is not the one I mentioned a few posts ago that has horizontal bolts and looks like the one in the source link. The vertical mount one is looking alot more appealing with the inclusion of the stock mounting hardware. The only question that remains now to find is what are the dimensions of one of the crosstrek bars and where the ideal mounting points would be on the cx-3.
Also in terms of practicality and installation, it seems that by using the vertical mount the only way to actually install it on the cx-3 would be from beneath. Moving the engine splash guard aside we would be able to get to the mounting points seeing as we have to install the actual bar with the bumper on given that the lowergrille does not come out and getting tools through it would be difficult.
