Next season Formula 1 will introduce the Halo with Nico Hulkenberg worried that it will disadvante the sport's heavier drivers.
Ahead of next year's debut of Halo, the FIA have raised the minimum weight of the cars to accommodate the device.
It is, however, proving tricky for the heavier drivers as the teams have found that even that increase isn't taking into account the full weight of the device and its mounting.

"We are aware of it, there is talk about it," Hulkenberg told Autosport.
"It's a political matter and the teams need to agree to change the weight, but some teams don't want to, so it's a bit of a situation.
"For me as a taller and heavier driver it's definitely going to be a bit of a penalty.
"The team have already told me there might be some overweight issues for me, and asked me if I could go to a diet.
"The answer was no!"
