After the Japanese GP, which noticed Lewis Hamilton end in seventh place, a group radio from the pit wall make clear a Ferrari setup alternative that proved much less efficient than anticipated. Right here is the complete dialog:
LH: “Sorry for that consequence, guys. Didn’t have the tempo at this time, however I’m grateful we proceed to push, subsequent races will likely be higher!“
BOX: “Yeah, thanks, good effort on the market. We’ll test collectively, in all probability a bit overbalanced all through defending the fronts. We are able to talk about later.“
What “overbalanced” and “defending the fronts” imply
The time period “overbalanced” refers to a automobile configuration the place the entrance grip is bigger than the rear grip, leading to a extra oversteering steadiness. This alternative is intentionally made by groups on circuits like Suzuka, referred to as “front-limited.” This time period refers to tracks the place the entrance axle tires—attributable to quick corners and frequent course adjustments—are essentially the most careworn. Due to this fact, 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 transformation enhances grip, thus lowering micro-slips that speed up tire degradation. Such a alternative doesn’t profit outright efficiency or perfect automobile steadiness, however it represents a compromise geared toward tire administration, with the aim of boosting race competitiveness. That is the which means of “defending the fronts.”
Such a consequence 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 transferring the aero steadiness ahead.
Lewis Hamilton was in all probability referring to this when, on the finish of qualifying, he said that the explanation behind a lackluster consequence in comparison with his teammate might need stemmed from setup decisions made by his aspect of the storage, targeted 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—based on the group 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 common requirements at this observe). Because of this, the tires required much less “safety” than groups had anticipated, rendering the setup alternative 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.
Due to this fact, the reason for Lewis Hamilton’s race tempo, weaker than his teammate Charles Leclerc who completed simply off the rostrum, was doubtless a setup that was too conservative when it comes to tire administration, which in the end compromised each pure efficiency and the automobile’s drivability.
