Im sorry but I never got and automatic emailed on the reply to this thread.
You need to use the stock metal mounting bracket that is at ether corner of the stock bumper, and put it in the stillen bumper.
I used the stock protection plastic piece under the new bumper but I don’t know if it will work for you since you have the retractable spoiler unit. Its probably a different piece then the US version. You might have to get creative. I have seen people not use the protection plastic piece and it works just fine.
It’s a strong bumper I don’t think you need to worry about wind. I would worry about those speed bumps, curbs and pulling into parking lots. My wife already scuffed mine trying to park at the mall.
I hope I replied in time
Also my grandfather was born and raised in Sweden. His last name was Lind. I hope to visit my roots some day.
