Awesome utility, everything works great, and the adjustment to camera clipping is a great addition, though I've got one suggestion:
I'm not familiar with editing cameras in NR2003, but I've done a lot of it in iRacing, and I'm betting the same concept applies here: in iRacing, there's an adjustment called NearPlane Bias that seems similar to what was adjusted here: adjust it too far one way, and you get the clipping issues we've had forever in NR2003. Adjust it too far the other way, and you get car LODs messing up. From what I've seen with the ICR mod, it seems like it may have been adjusted too far, so playing around with that to get the right value might be a good idea. Still, great change overall, and even with that small issue it's still much better than vanilla!
Note: the way I found it best is by using spectator camera at Las Vegas 2020 (from the Stunod downloads), so that'd be a good way to test it
and yeah i agree it definitely needs to be fine tuned
