Apparently Adobe Premiere ****** up the exporting of my videos, so they didn´t come out in the proper order, nor with the correct names, and they´re cut after 6 min each ... I´ll re-do everything tonight and upload them again !
To answer you Mr-Ben, I run standard discs, directly from my Renault dealer. They are enough for the track as they come from Laguna 3 in the origin, so almost too big for the Twingo. I´ve never had any warping, and actually unless you bring your discs to 3000°, they won´t warp. I guess what you describe as warping is when your discs actually get some brake pads powder glued to them because of the heat, then they vibrate when you brake.
Next year I´ll switch to aluminium center brakes with separate rotors, but the same size as original, and I´ll modify my air ducts to make them more efficient.
The shot is taken at the exit of the Werseifen corner (almost hairpin actually) before heading towards the Breidscheid bridge over the town of Adenau.
