Soul Help (Spoiler/Kammback)

This spoiler is not standard on all Souls, so Kia didn't see it as being necessary to the design.

Those lost Souls without it, did however get a small spoiler lip instead (nano-kammback).

or

And yes, it was a PITA to get off! For some reason Kia bolted and glued it on!

Waterproofing the mounting holes is probably the reason.




I've been looking at ways to (maybe ...) mount a Kammback on my V50 which is not unlike the Soul: near-vertical rear hatch, lights high up on either side.

I'd fix the Kammback to the hatch itself and glue small U-shaped mounting points low on either side of the rear glass, drill a hole through the legs, and use a secured pin to fix a bracing strut on the inside of the Kammback.


ZigZag tape or clear Turbulator "dimple" tape could be used as VGs on the sides, forward of where the rear lights angle inward, to try to get the airflow to make the curve and reattach to the Kamm.

At this point we are only trying the cardboard one to see if we improve the FE. We are thinking that the flat back has some serous aero issues and this might be a cheep fix.

Everything we are doing is reversible.

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.
