Cool car to look at, a lot of detail and textures are really well made. Wheels could be made up to par with the rest of the model though
The main issue i have with this car is the driveability, i do not know if your rear suspension type is the best way to replicate the suspension setup that the real car has, during compression it seems like the camber changes too much. Certainly goes the right way as the lower it goes the more negative it should be but dunno, it doesn't look as natural when you drop the car a few times in pit menu
Open diff is also propably the worst thing you can put on this car as it makes many things way more unpredictable such as getting one tyre fire out of exits in turns and under braking if you happen to turn in it becomes a twitchy mess that needs constant sawing with the wheel to stay under control. Those things cause the car to run out of optimal tyre temps so fast that these issues multiply. But yeah, i've no clue if it is the best way to replicate the original.
I was told the car didn't really have any other differentials and that much i can understand why it is limited to open diff only, maybe in the future if its possible to limit differentials into other types you could try viscous diff instead which is sort of an open diff with preload. It retains many of the charasteristics of the open diff but with the preload it keeps at least some power on the tyre with grip so you actually dont light up the inner tyre every time you want to make a turn
Lastly, the hitbox LOD causes issues. Currently it has an angled front and rear with the front being lower than the rear of the hitbox, causing any type of front to rear contact to lift the front car up a bit and when you do this online the cars desync a bit and can cause glitchy hits. I don't know if it can be seen on the vid above but i had one incident where i only barely touched another cars bumper and was sent into a 360 spin. Bumpdrafting was also of course, out of the question and i am willing to bet you could bumpdraft these in real life with absolutely no worry at all
Flat surface on both rear and front up to the bumper level would be optimal solution for this.
