The winds were lower and steadier today, so we went and did some testing.
Soulster and I tested spoiler on/off and cardboard Kammback on/off.
Results were:
Spoiler, no statistical difference.
Kammback, very limited runs showed no difference.
Notes on Kammback:
1, angle of cardboard Kammback is not right
2, Kammback was short (20").
3. transitions were not rounded.
1+2+3 = not a great test to show what is possible. Soulster and I feel that the effort to produce a Kammback for his car is not worth the time right now.
