After the Styrian Grand Prix, Renault lodged a formal protest against the legality of the RP20, suggesting its brake ducts (a part teams must design themselves) may be too similar to the Mercedes W10's. Brake ducts of the RP20 were impounded and stewards requested Mercedes provide brake ducts from the W10 for comparison. Renault also made an identical protest to the results of Hungarian Grand Prix regarding the RP20's legality. The same protest was repeated by Renault at Silverstone following the British Grand Prix. Ferrari submitted a request for clarification by the FIA on the same grounds as the Renault protest. The FIA upheld the Renault protests, fining Racing Point and deducting 15 points from the Constructors' Championship. It stated that while the car complied with the technical regulations, the design process of the rear brake ducts constituted a breach of the sporting regulations. Because Racing Point had based the design of the part on CAD drawings supplied by Mercedes, the FIA viewed Mercedes, not Racing Point, as the designers of the rear brake ducts. However, the design process of the front brake ducts was deemed legal, as the team had used a similar design in 2019, when teams were not required to design brake ducts themselves. The 15-point deduction was ultimately vital in their battle for third place in the Constructor's Championship. Although Racing Point scored the third-highest number of points, the point deduction demoted them to fourth place behind McLaren.
