2009 Technical Regulations.
15.5.3 An impact absorbing structure must be fitted behind the gearbox symmetrically about the car centre line with the centre of area of its rearmost face 300mm (+/-5mm) above the reference plane and no less than 575mm behind the rear wheel centre line.
The rearmost face of the impact structure must be a rectangular section no less than 100mm wide, this minimum width must be maintained over a height of at least 130mm and each corner may incorporate a radius no greater than 10mm. Between the rear face and the rear wheel centre line no dimension of the area thus defined may diminish nor may any part of the structure or gearbox which is visible from below, other than the permitted radii be higher than the lower edge of the rear face.
No requirement to maximum width, but a specific requirement for minimum 100mm wide.
Racing should be decided on the track, not the court room.
