Testing different angles and heights could give the best results without adding too much turbulence.

Good point.

I went seat of pants testing.

Started out with a huge NAStruck height rear spoiler, and later cut it down to half that height to find the sweet spot.

Found the correct angle (for me) via experimentation too.



In my opinion there is NO one one right way.

Totally dependent on what your goals are.

My goal was increased stability 60%, better aerodynamics 30%, looks cool 10%.

I'm not doing crazy rally racing, but I would like to get a bit better fuel economy
