Every message, in the order it happened
Engineer: It's about 20 seconds Lance, 20 seconds.
Sebastian VETTEL: Check the oscillations in the potentiometer.
Engineer: Yeah, copy that.
Engineer: OK, Lance, we'll be boxing this lap. Box, box, pit stop to a new set.
Nikita MAZEPIN: Smart push. Mode
Engineer: push confirmed.
Nikita MAZEPIN: Mode
Engineer: push confirmed.
Engineer: Morweys, Morweys, Norweys.
Engineer: Okay, brake balance one click rearward not sure about target lap time yet. Don't have enough reference info
Engineer: You can back off now. Jun's happy. Slow down.
Engineer: So positive on the brakes when you can. Got a decent forwards offset at the moment. Back to mode 12, mode 12.
Engineer: So try to attack less braking turn 6, carry more speed turn 6.
Engineer: We'll be boxing this lap Lance. Box, box. We can back off now. Tyres are good. Back off and box. Perez 12 behind on an out lap.
Engineer: Right toggle is available for stabilizing 6-7 if you need it.
Mick SCHUMACHER: Copy.
Daniel RICCIARDO: Okay, straight through.
Engineer: Straight through, starting pit exit, two burnouts, first gear launch.
Engineer: Ok Kimi, all your tires have been stabilized now, so all looking good outside.
Engineer: Ok Pierre, let's consider going up on the tours already, N37
Nicholas LATIFI: That's why I had some very harsh shifts for the start, but that's why.
Engineer: Copy, we have 1st and 2nd, need to learn 7 and 8 now.
Engineer: We're catching Schumacher quite quick. He's quite slow in front of you.
Engineer: How's the locking, Checo? B-Bell 2 is available if you need it.
Sergio PEREZ: Yeah, we are in a bad window with cars using the RS Saturn.
Engineer: Yeah, Checo, let's call this round at the end of this lap. We'll box at the end of this lap.
Engineer: When I come in for flap adjust, are you happy there?
Carlos SAINZ: Box 4.3 down.
Engineer: Confirm and box.
Engineer: Are we boxing this lap? We're boxing this lap, but keep pushing, keep pushing, so you can stay and go push.
Engineer: Can you try second gear turn eight and nine please second gear eight and nine
Engineer: Box this lap, big lift into the pit lane.
Lando NORRIS: Yeah, can't fail.
Engineer: Okay, final lap please Max, final lap.
Kimi RAIKKONEN: I'll light the bootlaps on myself.
Engineer: Copy, copy.
Engineer: Recharge on, stop short, lay rubber.
Engineer: Clutch position on target
Engineer: The rear tyres are hot. If you can do more on brake balance, plus two would be good. How is the balance? Do you need a flap adjust for the next set?
Lance STROLL: No, I don't. Just a bit of overheating on the rear.
Engineer: Copy. Two to go. No adjust for the next run.
Engineer: So we're thinking of four more laps on this one, four more full-time laps. Rears are very hot now. So 10.11, try opening the entry just to reduce sliding on the exit of 10.11.
Engineer: And cool down the engine now, cool down the engine, boxes up.
Engineer: You want to reset B-bell to zero for the pit stop?
Nicholas LATIFI: Fox, Fox, Fox, Fox
Engineer: Copy, one shot, right line, pit limiter
Engineer: One more time, one more time.
Engineer: Okay, how's the tire? How's the dig?
Mick SCHUMACHER: Good. It was just a front lock that is annoying. I didn't want to see a competitor at all.
Engineer: OK, lads, we may be close to Sebastian on pit exit. We can go white button and plus five straight away. White button, plus five. Caution, Vettel pit exit. Caution, Vettel pit exit. White button on.
Sebastian VETTEL: Can I have error balance check? Error balance check?
Engineer: Yeah,
Sebastian VETTEL: let's go down. Two clicks.
Engineer: Copy, understood.
Engineer: Valtteri's just started his run, he's a 14.1 but less management
Engineer: Okay, rear brakes are good and we're happy with the tyre management, so this is a good pace.
Engineer: So main losses were 10-10 and the rotation on previous laps. Lewis doing more management, lift and coast at 4, management exit of 6 and 7.
Engineer: and Valtteri 14-9 losses at turn two and entry turn four
Engineer: So we think you'll need more rear tyre management, more rear tyre management, so turn 6, 7 and 11.
Engineer: Press and hold the overtake. Press and hold overtake.
Engineer: You were on target, there was some wheel spin, but your release timing was good.
Engineer: So how's the low speed balance?
Sergio PEREZ: It's quite understeery.
Engineer: I recommend torque 6, torque 6.
Engineer: suggest brake balance plus two clicks brake balance plus two
Engineer: Box this lap Lance, box this lap for lay rubber, lift off for the PU, box this lap for lay rubber. Reset brake balance, no white button.
Engineer: From Mosses to Maxwell, turn two, mid-corner.
Max VERSTAPPEN: No, the tools are fine, just managing tires.
Engineer: Roger that.
Engineer: And consider pushing a bit less entry on 4 to focus on exit.
Engineer: And we need another two laps before we achieve the sustained rear tyres.
Engineer: Guestman, how's the balance so far?
Esteban OCON: Yep, balance is fine. Let's
Engineer: see
Esteban OCON: how it evolves.
Engineer: Daniel if you want to try less front wing we can box this lap, if you want to try less front wing we can box this lap.
Daniel RICCIARDO: Okay yeah let's try, let's just go two two
Engineer: turns down. Copy, box now.
Daniel RICCIARDO: Try a proper step, box confirmed.
Engineer: Norris lap time in medium 13.6
Engineer: So Giovinazzi six lap old softs ahead and Ocon five seconds behind six lap old softs
Engineer: If you can't pass Kimi we'd like a couple of laps no following which means backing up to Latifi seven behind
Engineer: Okay, let's push next lap and then start managing push next lap and then start managing
Engineer: So eight to go eight to go start to manage the tires, please
Engineer: So you're all clear behind, we'll have a start from end of pit lane.
Sergio PEREZ: I'm having some vibrations, one,
Engineer: two, three. Yeah, copy that, Choco. We can see it. So Max's last lap of 13.3.
Engineer: I
George RUSSELL: just feel like the tyres are absolutely nowhere, they're sliding all over the place.
Engineer: I
George RUSSELL: mean the ball seems really high on one side, pretty cold on the other.
Engineer: The
George RUSSELL: surf is very high.
Engineer: Okay, you'll have one more lap and we want to have a 40% lift in 11 on that lap. 40% lift.
Engineer: The tires are pretty good you can lean them on lean on them more in 6.7
Engineer: S1, we're going to delay this by a lap please, so we're going to finish this lap and then box please, so drive past the pit lane this lap
Esteban OCON: Copy that, I'm happy to box to save engine though
Engineer: I'm pretty sure that's because of timings, drive past the pit lane
Engineer: And Lewis 12-7-by is in traffic.
Engineer: So one more timed, one more timed, happy to push, happy to push this lap.
Engineer: I
Nikita MAZEPIN: struggle when I'm close to other cars, similar to Mexico, when we lose downforce, it's really tough.
Engineer: Understood, Perez behind is boxed and two more to go, two more to go.
Engineer: Okay, box, box, end of session.
