Raising,pushes the center of gravity higher (not good) and increases roll moment (not good).
It also exposes more tire to the air,increasing frontal area (typically not good).
It is true that raising the car up out of ground effect will cut the body drag in half,but you'd lose all practicality.(A wing-inspired solar racer on a closed race course yes,any other scenario,no).

blocks of wood would do it. That is the easy part, coming up with the full size tunnel is tough.
