Has anybody seen in Nurburgring how flexible the BAR rear wing is?
From the on-board camera facing backwards it was very clear that the rear wing was flexing. Is it allowed? How flexible it can be? What are the tolerances? Does anybody know?

Flexing is possible but....the car has to pass a static test on the wings....where the wing has do withstand a determined weight without flexing.
The tests are made during Scutineering.
On the front wing they put 25 Kg of ballast on the end plates. and on the rear wing they pull down the rear wing main element....50kg if not mistaken.
I couldn't find the correct amouts of balast that is put on each wing...these are the numbers I can remember. These tests were introduced in 1998 after in 1997Ferrari introduced the flexing wings.
I'll post back when I find the article number from the FIA regs....I took a quick look and didn't find it.

Back with the Tech regs transcript:
3.17 Bodywork flexibility :
3.17.1 Bodywork may deflect no more than 5mm vertically when a 500N load is applied vertically to it 700mm
forward of the front wheel centre line and 625mm from the car centre line. The load will be applied in a
downward direction using a 50mm diameter ram and an adapter 300mm long and 150mm wide. Teams
must supply the latter when such a test is deemed necessary.
3.17.2 Bodywork may deflect no more than 10mm vertically when a 500N load is applied vertically to it 400mm
forward of the rear wheel centre line and 650mm from the car centre line. The load will be applied in a
downward direction using a 50mm diameter ram and an adapter of the same size, Teams must supply the
latter when such a test is deemed necessary.
3.17.3 Bodywork may deflect by no more than one degree horizontally when a load of 1000N is applied
simultaneously to its extremities in a rearward direction 780mm above the reference plane and 130mm
behind the rear wheel centre line.
3.17.4 In order to ensure that the requirements of Article 3.15 are respected, the FIA reserves the right to
introduce further load/deflection tests on any part of the bodywork which appears to be (or is suspected of),
moving whilst the car is in motion.
