Red Bull RB4 - V-cut on rear wing flap 13 May 2008
A small but interesting change was introduced on the RB4 in Turkey, following on from the big aero overhaul debuted at the previous round in Spain, and it's one that will play an even more relevant role at the next race in Monaco. A deep V-shaped cut was placed in the middle-top of the rear wing flap, providing a vent for the high-pressure airflow impacting the wing profile in this area. Its purpose? To reduce the increased drag generated on the straights when running the kind of high flap angles essential on a tight, twisty circuit like Monte Carlo.
