I love this author for the fact that he not only mindlessly inserts other music on top of the gameplay, but also makes it a kind of "part of the game" (attenuation in tunnels, stopping in case of accidents). Love you very much❤
Considerating how pro Street physics are, this feels weird. The BMW looks great tho. Funny how there is an IA which uses the BMW M3 GTR vinyl but with aftermarks and other colours. Im personally doing a 100% Pro Street playthrough (sadly I couldn't get the "extra" events that gave you a free car; Silvia, IS300, Vette, Cayman.. to extend the playthrough). IT is quite enjoyable to just use one car for every type of event. On this case, Im using the 240sx delivery of RC (I couldn't get the mods so I just did them myself).
I'd find the original physics weird as well, were I to return to them. Do you have patch v1.1 and the DLC unlockers in place? If you do, make sure to dominate the race days at the ends of the career map "branches". Those bonus race days are often hidden until you dominate the nearby ones.
