In fact it's not grey but rather black and white there, right?
FIA wrote:3.10.4 Any bodywork behind the rear wheel centre line which is
more than 600mm above the reference plane, and between 75mm
and 480mm from the car centre line, must lie in an area when
viewed from the side of the car that is situated between the rear
wheel centre line and a point 350mm behind it. When viewed from
the side of the car, no longitudinal cross section may have more than
two closed sections in this area. Furthermore, the distance between
adjacent sections at any longitudinal plane must not exceed 15mm
at their closest position.
In order to ensure that the relationship between these two sections
cannot change whilst the car is in motion they must be bridged by
means of rigid impervious supports (including any adjustment
mechanism) arranged such that no part of the trailing edge of the
forward section may be more than 250mm laterally from a support.
These rigid supports must :
- fully enclose the two complete sections such that their inner profile
matches that of the two sections. Their outer profile must be offset
from the inner profile by between 8 and 30mm and may not
incorporate any radius smaller than 10mm (‘gurney’ type trim tabs
may however be fitted between the supports) ;
- not be recessed into the wing profiles ;
- be arranged so that any curvature occurs only in a horizontal
plane;
- be between 2 and 3mm thick ;
- be rigidly fixed to the two sections. Some form of adjustment
mechanism between the sections may be incorporated for the sole
purpose of allowing adjustment of the sections relative to one
another whilst the car is in the pits ;
- be constructed from a material with modulus greater than 50GPa.
These supports will be ignored when assessing whether the car is in
compliance with Articles 3.9.1, 3.9.2, 3.10.1 and 3.10.5.
I shouldn't have been so lazy and read the regs
before posting this one. I hope that at least I created some sort of distraction from the spygate, safetycargate etc. topics.
