So far, the magnets hold at approx 110kmh. It also depends on wind conditions. I chose these magnet size also considering the aesthetics, as I didn't want to have there to big magnets. Might be, they will not hold at very high speeds. I am still experimenting, didn't try higher speeds. On the other hand, when raining, I seldom drive at high speeds.
The quadratic magnet is 5x5x5mm and holds around 1,5kg. The round one has a diameter of 10mm and holds also around 1,5kg. The bond I used is a 2K Bison Power Polyurethane Bond, as it is more elastic. Probably any epoxy bond will do.
If You are following with the plastic "stiffeners" described above, avoid any sharp edges, not to hurt the synthetic leather when imposing it. A bit silicone smear will facilitate it. Round both ends and inner edges.
