Depending on the car model, it may be necessary to remove the rear bumper in order to fit the towbar. Incorrectly removing the bumper may result in difficulties during reassembly as well as permanent damages to the bumper's fastening elements.
In some cases, it is necessary to undercut the bumper. These are divided into two types - visible and invisible, which in the vast majority of models can only be seen when looking from the bottom. Information concerning the necessity, shape, and size of the cut can usually be found in the assembly instructions
Although no qualifications are required to install a towbar, bearing in mind the above, we recommend having it installed in a professional car workshop.
