From what has been said and the race speeds of the redbulls they seem to have a very good aero package, so maybe the ride height thing isn't a big deal (if it does exist) but maybe giving them the edge in qualifying. I'm sure some of the other teams will have their share of bad luck at some point in the season, as Ferrari have kind of already had by having to use up an engine for both drivers before the start of Bahrain, it didn't lose them points but could have an impact later in the season especially if they have another failure.
