After the Japanese GP, which noticed Lewis Hamilton end in seventh place, a workforce radio from the pit wall make clear a Ferrari setup alternative that proved much less efficient than anticipated. Right here is the total dialog:
LH: “Sorry for that end result, guys. Didn’t have the tempo right now, however I’m grateful we proceed to push, subsequent races shall 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, often known as “front-limited.” This time period refers to tracks the place the entrance axle tires—attributable to quick corners and frequent route adjustments—are probably the most harassed. 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 variation enhances grip, thus decreasing micro-slips that speed up tire degradation. Such a alternative doesn’t profit outright efficiency or very best automobile steadiness, but it surely represents a compromise aimed toward tire administration, with the aim of boosting race competitiveness. That is the that means of “defending the fronts.”
Such a end result could 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 acknowledged that the explanation behind a lackluster end result in comparison with his teammate may 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—in line with the workforce 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 standard requirements at this monitor). In consequence, 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, corresponding 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 probably 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.
