That gap is pretty small (2mm which is within the 3mm body tolerance), also I will make the auxiliary fuel tanks removable along with the updated thumbnails.
I took the mirrors from the eSBR and I also do notice that the eSBR's mirrors aren't perfect either. Edit: Don't worry I got it fixed. Shhh that is the point, car manufacturers do understate horsepower by a bit.
I tried the mod and i like it so far. Visual stuff for fixes: 0.(you still have cameras and lights in dae) 1. Sharp holders is out of place on curvy body. Glass misaligned or whatever that is and etc. , , , 2. UV issues: , , , 3. Apparently all that dragging down the vertices destroyed the polyflow, there're visible shading issues. Door one i fixed just by this, didn't check uv changes (no idea how will you fix the left problem)
For the side vent UV issue, there is a hotfix incoming (that will use the grille_hex texture) although it is not 100% perfect, it is much better and it will be easier to fix in the future if needed. For the rest, I will definitely take the time to examine the visual issues you have highlighted, and the next update after the upcoming hotfix will be focusing on minimizing if not fully eliminating them. Aside from that I will also add a small vent cover (much like the real life Audi R8) that will protect the engine bay better but not reducing too much of the airflow. Appreciated the things you pointed out!
