27 August 2011 - McLaren MP4-26 - brake duct aero development
 
Brake ducts are ever evolving and becoming increasingly important as aerodynamic devices. As well as attaching aero fins to the inside, teams - including McLaren - have started to mimic the effect of the wheel rim covers seen in previous seasons (but now banned) with complex-shaped brake ducts which better control the flow of air around the outside of the wheel. This drawing shows the rear brake drum on the MP4-26.
27 August 2011 - Ferrari 150° Italia - front wing variations
 
Ferrari have opted to use two different front wings for the qualifying session and race in Belgium. Massa decided to stay with the one he used in Canada, whilst Alonso is running with a new version. Tested in Hungary, it features Red Bull-inspired upper flaps (red arrow), and a single main flap instead of the previous double solution.
27 August 2011 - Mercedes MGP W02 - revised front wing
Mercedes have brought another evolution of the front wing they introduced in Hungary to Spa. As well as the additional upper flap, which was inspired by the Red Bull, there is now an additional vertical fin (large red arrow) to better direct airflow. The team have also modified the system used to adjust the flap's angle of incidence by moving it from its previous central position (where the new fin now is) to the side of the endplate (small red arrow).
28 August 2011 - Toro Rosso STR6 - new nose design
Toro Rosso brought a brand new nose to Belgium. Taller, flatter and longer than before, it's similar to that used by Mercedes and will improve airflow in the car's lower sections. It passed its required crash test on August 4.
28 August 2011 - Red Bull RB7 - brake duct development
Red Bull brought two different rear brake duct solutions to Belgium. This one was used by Sebastian Vettel. It has a sophisticated shape behind the brake disc, similar to that used by McLaren, to better channel air to the outside of the wheel rim.
