Red Bull RB4 - front wing endplate ballast 03 November 2008
Not strictly a change, but much more visible in Brazil thanks to David Coulthard's one-off white livery, was this interesting detail regarding Red Bull's placement of ballast in the front wing assembly. As on most cars, the RB4 has tiny blocks of wolfram/tungsten inside the wing's main profile, hidden from view within covered housings. But in addition to this 'standard' ballast placing, the RB4's endplates also have detachable covers which hide extra ballast housings (inset). The housings may look small, but the high density of the ballast metal means they can carry around seven kilograms. This allows the weight distribution of the car to be moved forwards slightly, improving its overall balance.
