Great map! I personally love how slick the Rainy Racing map is. I'll even admit I was pressing the throttle aggressively on my controller just out of habit, as if I were actually driving on the track itself (I tend to make subtle movements/reactions whenever I'm playing Beam, it's normal I guess lol)
However, my only complaint is that same Rainy Racing map tends to kill my framerate, which I would normally expect from the Day 2 Maps since those have crush cars and whatnot. My specs are as follows:
NVIDIA GeForce GTX 1660Ti
64GB DDR4 2400 RAM
Intel Core i7-9750H @ 2.6GHz
Definitely a great map with a lot of nostalgia. I did have to turn off shadows to get a better framerate, but that's negligible.
The one thing I would suggest is maybe add a freestyle variant or something similar to when trucks like Avenger came out during the field without having to rely on the Encore Variants. It might be a lot to ask, but it could really make this mod shine even more in terms of realism; it's already beautiful as it is!
