2.3 was spot-on, but there's something quite wrong with 2.3.1. On the NSX-R, it feels like either a lot of toe changes in the rear (under both braking and acceleration) or a totally open diff on decel. Or both. The car now requires constant maintenance throttle mid-turn, but the amount needed then usually results in a spin-out on corner exit (where a mid-engine car ought to feel the most stable). I'm using the 90's street tire btw, but the regular street tire isn't much better. If the real NSX-R felt like this, it wasn't much fun. I wonder sometimes if putting in *exact* suspension settings from the real car necessarily results in an accurate simulated car. Even F1 teams have correlation issues between their supercomputer-powered simulators and what they get on-track. It stands to reason that AC is no different. In any case, you're talking to someone who's driven an NA1 Acura NSX (not the R, I'm American) back in 2003 (belonged to a dermatologist friend), and it was far more stable than this on corner entry. 2.3.1 feels like the time I dialed in some toe-out on my S2000 (thought it would help me during an autocross, all it did was help me spin repeatedly under braking).
