3.7 Front bodywork :
3.7.1 All bodywork situated forward of a point lying 330mm behind the front wheel centre line, and more than
250mm from the car centre line, must be no less than 75mm and no more than 275mm above the
reference plane.
The Skid Block was introduced as part of the safety changes that followed Ayrton Senna's death.
The plank does not in itself restrict airflow under the car. It is used as a gauge which restricts the minimum ride height attainable by the car. The closer the car is to the ground, the more efficient the front wing and rear diffuser. The higher the down force levels, the faster a driver may corner. Cornering at high speed is considered excessively dangerous and so the skid block was introduced to counteract this.
3.17 Bodywork flexibility :
3.17.1 Bodywork may deflect no more than 20mm vertically when a 1000N load is applied vertically to it 800mm
forward of the front wheel centre line and 795mm from the car centre line. The load will be applied in a
downward direction using a 50mm diameter ram to the centre of area of an adapter measuring 300mm x
150mm, the 300mm length having been positioned parallel to the car centre line. Teams must supply the
adapter when such a test is deemed necessary.
The deflection will be measured along the loading axis at the bottom of the bodywork at this point and
relative to the reference plane.
3.17.2 Bodywork may deflect no more than 10mm vertically when a 500N load is applied vertically to it 450mm
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 925mm above the reference plane and 20mm
forward of the forward edge of the rear wing endplate.
3.17.4 Bodywork may deflect no more than 2mm vertically when a 500N load is applied simultaneously to each
side of it 200mm behind the rear wheel centre line, 325mm from the car centre line and 970mm above the
reference plane. The deflection will be measured at the outer extremities of the bodywork at a point
345mm behind the rear wheel centre line.
The load will be applied in a downward direction through pads measuring 200mm x 100mm which conform
to the shape of the bodywork beneath them, and with their uppermost horizontal surface 970mm above the
reference plane. The load will be applied to the centre of area of the pads. Teams must supply the latter
when such a test is deemed necessary.
3.17.5 Bodywork may deflect no more than 5mm vertically when a 2000N load is applied vertically to it at three
different points which lie on the car centre line and 100mm either side of it. Each of these loads will be
applied in an upward direction at a point 380mm rearward of the front wheel centre line using a 50mm
diameter ram in the two outer locations and a 70mm diameter ram on the car centre line. Stays or
structures between the front of the bodywork lying on the reference plane and the survival cell may be
present for this test, provided they are completely rigid and have no system or mechanism which allows
non-linear deflection during any part of the test.
Furthermore, the bodywork being tested in this area may not include any component which is capable of
allowing more than the permitted amount of deflection under the test load (including any linear deflection
above the test load), such components could include, but are not limited to :
a) Joints, bearings pivots or any other form of articulation.
b) Dampers, hydraulics or any form of time dependent component or structure.
c) Buckling members or any component or design which may have, or is suspected of having, any
non-linear characteristics.
d) Any parts which may systematically or routinely exhibit permanent deformation.
3.17.6 The uppermost aerofoil element lying behind the rear wheel centre line may deflect no more than 5mm
horizontally when a 500N load is applied horizontally. The load will be applied 950mm above the reference
plane at three separate points which lie on the car centre line and 190mm either side of it. The loads will be
applied in a rearward direction using a suitable 25mm wide adapter which must be supplied by the relevant
team.
3.17.7 The forward-most aerofoil element lying behind the rear wheel centre line and which lies more than 730mm
above the reference plane may deflect no more than 2mm vertically when a 200N load is applied vertically.
The load will be applied in line with the trailing edge of the element at any point across its width. The loads
will be applied using a suitable adapter, supplied by the relevant team, which :
- may be no more than 50mm wide ;
- which extends no more than 10mm forward of the trailing edge ;
- incorporates an 8mm female thread in the underside.
3.17.8 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.
