A few pictures of the changes on the car. Also a picture of the wheels that will be used with Michelin Pilot Sport Cup tyres as soon as the weather will be better. As you can see, the daughter's driver training has already started
@///Mster: removing the sunroof was in fact pretty easy. I asume you know how to remove the sunroof from the car? Just remove the headliner, and you'll see all the screws. Easy.
Then you can remove the part that's visible from the outside, and reuse that to fill the hole:
We used 2 metal pieces of 1 or 1.5mm thick, about 10cm wide, and a little longer than the largest part of the sunroof. You'll see that the roof is reinforced right next to the hole of the sunroof. We attached the 2 metal pieces to these reinforcements with urr, don't know the English word, could it be something like 'blind nails'? Then, when looking from above, the 2 metal pieces cover a part of the sunroof hole. Then we used tons of silicon on the 2 metal pieces, and put the original sunroof on the silicon. Shaked a bit, and made sure the sunroof was somewhere in the centre of the hole. Made sure the sunroof was at the correct height, pushed a bit extra where necessary. Then let it dry, and seal it off with silicon. Done...
I attached a picture of the inside of the sunroof. The 2 red shapes are around the metal pieces, the black lines are around the 'blind nails'. It's a bit more difficult to see, since it's already sprayed white on this picture.
The 2 red shapes cover at least 7 cm of the sunroof hole.
