Gearbox rating / car overall rating

[RavenDark]

Alright, thanks for the explanation.

I had already modified the values in the components.xml, but they had no effect on the overall gearbox rating, that's why I asked.
But no problem, I'll then keep on producing crappy gearboxes and try to examine some other bugs I recently found (though many of them have already been mentioned here in the forums by Arakash or Frankschtaldt).
