We will have a big update, according to Verstappen, to the RBR.
The moment whit a team near them (McLaren) can be already over.
A new big update? Verstappen is already dominating the season and Red Bull will make sure that it stays that way then. McLaren really got quite near Red Bull taking the British GP into account. Verstappen couldn't finish the race with a big gap by opening it quickly right after SC. This was promising for us to watch a little more competitive races but this news isn't good at all.
I don't think much thing will change for Perez though. Because his main problem is his individual mistakes. Even if he is given a faster car than Verstappen he would still tend to mess it up by making mistakes now.
