Hi! This is my first MOD ever. Not really a mod, but yeah. It will make the road/surface very smooth and sensitive. If the road touches the top of the car, it will turn very fast that sometimes, your car will fly. But be careful, sometimes you'll fly until you drop into the sea. I'll post some screenshots.
Installation
1) Extract the Surface folder
2) Bring/drag the surface.dat and replace it in your data folder.
3) Restart and enjoy!
