Let me know if it works!
Update on the T400R. I only have the seatbelts left and then the 3D elements should be finished. I included new brake calipers (not exactly the best but I think they are acceptable), two gear levers (one like the classic GTR2 one and one that I saw on the chassis used in 2001), I redid the rear wall and fixed some elements like switches. I finished the motec and added some elements on the left (I still have to finish but I think it's okay since I don't know exactly what's there). Then I only realized yesterday that the headlight arrangement was wrong. The little headlight on the outside is not the indicator and I had to reverse everything.
Physically it works now, but I know that there is still work to do. On an aerodynamic level it was a mess and I most likely made a few mistakes.
Obviously I don't post screenshots to show how (not) good I am. If something doesn't convince you or is poorly done, don't worry about letting me know. The car will obviously be free and available only here on GTPlanet. Santa Claus is just waiting to put it in the sack LOL
