For me as a graphic designer it will be good to can upload skins with 4096 resolution bcs more resolution means more details. For example all my skins are 4096px.. This is one of my best skins who i create with max resolution. (5120x4096 - real size of XRT)
This is how looks like xrt with 55 degree. Its fun for me but xrt do not have enough power to keep that angle. Its fun to get into a corner with your doors but you cannot keep this angle if you dont drive with high speed on some big layout for example or your tires are not hot.
Okey i was sure need to add more info and pics maybe. I made before drift touge (this on the pic) and it will be very nice to can slide between dark and light zones. On the pics of the report i saw there is no floodlights arround this small road:
Also your idea for mobile floodlights is very nice.
