After the Japanese GP, which noticed Lewis Hamilton end in seventh place, a crew radio from the pit wall make clear a Ferrari setup selection that proved much less efficient than anticipated. Right here is the complete dialog:
LH: “Sorry for that end result, guys. Didn’t have the tempo as we speak, however I’m grateful we proceed to push, subsequent races might be higher!“
BOX: “Yeah, thanks, good effort on the market. We’ll test collectively, most likely a bit overbalanced all through defending the fronts. We are able to focus on later.“
What “overbalanced” and “defending the fronts” imply
The time period “overbalanced” refers to a automobile configuration the place the entrance grip is larger than the rear grip, leading to a extra oversteering steadiness. This selection is intentionally made by groups on circuits like Suzuka, often called “front-limited.” This time period refers to tracks the place the entrance axle tires—because of quick corners and frequent path modifications—are probably the most harassed. Subsequently, to enhance race tempo, these are the tires that have to be managed as a precedence.
Groups, to this finish, deliberately shift the automobile’s steadiness to extend vertical load on the entrance axle. This alteration enhances grip, thus decreasing micro-slips that speed up tire degradation. Such a selection doesn’t profit outright efficiency or ultimate automobile steadiness, however it represents a compromise geared toward tire administration, with the objective of boosting race competitiveness. That is the which means of “defending the fronts.”
Such a end result might be achieved by altering the mechanical setup—for instance, rising rear axle stiffness or softening the entrance one, adjusting suspension parameters (like camber and toe), and shifting the aero steadiness ahead.
Lewis Hamilton was most likely referring to this when, on the finish of qualifying, he acknowledged that the explanation behind a lackluster end result in comparison with his teammate might need stemmed from setup decisions made by his aspect of the storage, centered primarily on the race.
Why the selection turned out to be too conservative
But when Ferrari tailor-made the setup to favor race efficiency, why—in keeping with the crew radio—did it not repay? The principle reply lies within the tire degradation in the course of the GP, which was surprisingly decrease than anticipated (and in comparison with regular requirements at this observe). Because of this, the tires required much less “safety” than groups had anticipated, rendering the setup selection pointless, because it didn’t ship the anticipated benefits. Regardless of that, Lewis Hamilton nonetheless needed to face the downsides of an oversteering steadiness, comparable to instability in quick transitions and traction phases, which hampered his efficiency.
Subsequently, the reason for Lewis Hamilton’s race tempo, weaker than his teammate Charles Leclerc who completed simply off the rostrum, was probably a setup that was too conservative when it comes to tire administration, which finally compromised each pure efficiency and the automobile’s drivability.
