This will hardly be noticeable. This small shift may have a bigger impact than you expect. Tests have shown that adding a loaded skibox (around 50 kg, as most cars aren't allowed to carry more) to a car decreases it's stability. The change in COG will be comparable to adding a Toppola. I hope you can agree that any change in COG causing it to go up, will decrease your stability. Then to put everything into perspective. If you were to drive a car with a Toppola, I suppose the increased susceptibility to crosswinds has a much greater greater impact on it's use than the change COG has. Usually you can avoid situations causing weight shifts by adjusting your speed, but you cannot avoid the weather. Mark
