The McLaren chief wants a penalty that would be a deterrent, such as an exclusion, should it come to light that Red Bull did break parc ferme rules. Zak Brown wants a signed affid

McLaren boss Zak Brown warned on Friday of "massive consequences" if champions Red Bull were found to have breached Formula One rules on adjusting car set-ups during closed 'parc ferme' conditions.

While the triple world champion is focused on his on-track battles with close friend Lando Norris, the tension between their teams continues to escalate. Red Bull had McLaren's 'mini DRS' rear wing banned after Baku, and McLaren retaliated with the T-tray controversy during the Austin weekend.

He has transformed the team, which snatched the lead in the constructors’ championship from Red Bull a month ago.

Red Bull allegedly has a device in the RB20 that allows it to alter the clearance of its front bib from inside the cockpit.

During the FIA Press Conference on Thursday, McLaren driver Lando Norris declared that regardless of how the season ends, it will be a year for himself and McLaren to be proud of. On Friday his boss echoed that sentiment.

After admitting to having a device that can alter ride height and bypass steward inspections, Red Bull have agreed to make the appropriate changes. This commitment was made after discussions with the FIA.
