 Wow :jealous: |
There were few drops of water that had run along the surface of kamm, but without gopro or someone to drive behind it is bit problematic to do tuff testing.
It might be bit steep, but especially from top angle is less than previous setup as now I bended edge of the kamm and that did stiffen it up nicely.
I still need to cut bit from leading edge to make it match size of trunk, also car will get dark grey to bits that are red now.
Reason for passing MOT with kamm was that there were no rule that could be used to prevent that, but tester clearly did not want to approve it.
I think that kamm starts to work properly only after there is flat area under the trunk, it is now such that rest of the bottom of the car is bit below rear bumper level, but under trunk it is almost at bumper top level, so there is that large empty area and rear bumper acts as kind of parachute.
