I liked this mod at first, but then found myself wishing for a way to tone it down. I totaled my car just from literally hitting a blade of grass (okay a small bush). And, I would get into situations where I would be off the road, but the 'reset car' option wouldn't pop up, so I had to further destroy my car trying to slide further down the mountain so I could reset it. It's mostly from deformation messing up your wheels. I wish there was a damage mod that would fulfill the goal of enhancing the suspense but not end your race so easily. There is a need for some middle ground.
I ended up going back to original damage, and was going to give the mod 3 stars, but I am giving it 4 because it is useful as a practice tool.
