[Monster Hesh]

The 'Halo' it self is made by three different FIA picked companies. The teams then get to pick which supplier they want. Whether these companies are allowed to be innovative with their materials structures etc: to meet the regulations but also be more competitive; weight, size, etc, is something I would like to find out, or whether FIA have supplied the complete specification.

Aerodynamic regulations for the F1 2018 championship allow a 30mm(I originally said 20mm) "wrap" zone around the Halo for fairing. This is tight to try and tidy up the aero impact, but there is scope for potential vortex generators and management.

As Jody mentioned about the weight, the biggest weight probably has come from creating the support structure within the chassis. All of which will be in excess of what the FIA allocated. Solutions will probably be a broad range and consequently as Jody said, wide lap time deltas.

A couple of piccys from the Abu habi test.



As you can see McLaren had, quite frankly, a lovely bit of aero porn on top of the halo. 3 tiered element aiming to generate vortexes, with a tailing edge at the back of the halo to channel the airflow close to the sides of the airbox and not disrupt airflow to the rear wing.

P.S. I don't really know what I'm on about.
