Going to get it plastic welded all being well, not cheap these bumpers!Yes that can be repaired, it could be plastic welded or you can use some epoxy glue and a bit of filler etc.
Zip ties as in drift stitching haha!zip ties.
"quick release" fasteners.
Alternatively, let my main man on products advise you on which adhesive you should look at....
Bodyshop will be able to repair that no problem. Theres a mega strong trade adhesive/epoxy for stuff like this possibly made by 3m from memory.
Everything can be repaired... To what standard is a different discussion. Those bumpers are pretty cheap though, buy second hand straight one.
Erm.........
I work for bmw as a Senior ATA Panel Technician. Yes it can be plastic welded, hot stapled, epoxy glued, reinforced with matting behind it .... but... with it being a mounting point with the 30 torx bolt in it the chances are it's going to break off again. Depends on how good of a job you want really. R56 jcw? You got a reg I'll see how much brand new
Single iirc?
