I might see if i can get permission to fix this up. I'm 100% new to modding in this but i've bug around in game files and played with tires and engines. Not sure what would need to be fixed but i'll download it now and play around with it.
One word, repeated multiple times: BEAUTIFUL! you have done this mod extremely well, i loaded it (btw no car screenshot at load vehicle screen) and I was 100% speechless/
This mod is almost 3 years old and has had no updates since then. Author hasn't been active on forums since the end of 2015. This mod is old and outdated, so you can't really expect it to work. What you can do now is: 1)Forget about this and move on 2)Try to fix it yourself(Which I'm almost sure you don't have the neccessary knowledge for) 3)Wait for someone else to fix it(Which I doubt will happen) 4)Watch some old Youtube videos and enjoy the nostalgy of how fast has time passed since then. Next time please check the date, when mod was uploaded and last updated. Mods this old usually never work.
