"SMP Racing BR03 Prototype"
Grab it
here or
here. In archive you will also find some tracks: Nizhny Novgorod Ring (NRING Circuit), Kazan Ring, Sochi Autodrom and Fort Grozny Autodrom.
P.S. from me: I tested the prototype yesterday - amazing and fun to drive!
3D-model is good, maybe a little lack of better AO and some better textures and some CSP features. Also, BR03 is positioned at the LMP3 level of performance, but how true this information from the SMP is - needs to be checked.

As for the tracks in the pack, I did not have time to check them and therefore I don’t know if they have any differences from those releases that were here earlier in the thread.
