Hello,
Yes i forgot to mention that you need to cut those 2 central pillars in order to fit nicely.
The bending process is pretty difficult. You can try to warm the lip with a heathun.
Mine was put directly on the car and bended on the car.
It is a pretty difficult operation because the 5f bumper is straight, not rounded as it is on 1m and 1p.
Unfortunetly i dont have a fitting
guide, we just measured the lip to be aligned and mounted it as it was.
I didnt try the heatgun solution but i`ve heard that it`s a much easier operation.
