Like other reviewers I really struggle with how to rate this. I'm going with 1 star to get the attention of the mod devs. The visual model, sound, interior, and breadth of NSX models are excellent.
The driving dynamics/physics, however, are terrible. With any slip the tires heat up to red almost instantly causing them to lose basically all grip (no other car does this). As soon as any slip happens in a turn the car oversteers and spins out. The car is very unstable under braking and as a result often spins.
I appreciate that the devs were going for the 'tricky' handling that the NSX is known for. I believe the 2.0 struck the right balance between will-bite-you-if-you-don't-drive-well and un-driveable. This does not.
I keep wanting to drive it because it looks and sounds SO good. I think maybe I just need to drive more carefully and smoothly or something. Then I drive it and even tip-toeing around I barely manage a lap before quitting in frustration. This is NOT how a car should drive.
Please, PLEASE, fix the physics. Just give us the 2.0 physics with the 3.0 car model! This would be an easy 5 stars with that! And finally, I do really appreciate the massive amount of work that must have gone into this mod.
