Well done - great perspective.

Better get used to the fin because it is here to stay unless there is a significant change in the aero regs - and is scheduled to become part of endurance racing in 2011.

According to the designers it is there to negate lift, and ensure stability. The whole Mclaren approach is to ensure a quicker line through corners, especially slow ones [which MUST make Jenson happy because that is where he is so good at gaining time, similar to Alain Prost].

It reduces the "yaw" of the car and keeps it grounded. Ground effects from the top down - I suspect that if the cars are vry quick through the corners, the FIA could well ban it for 2011.

Mclaren have the best look I think and have the most beautiful car - and that is not because I support Jenson.

Interesting, I was under the impression that the fins main job was to help clean the airflow to the rear wing during yaw so that it produces more downforce mid corner (though obviously by braking up airflow gowing laterally across the car it reduces lift as well).
