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 right now, however I’m grateful we proceed to push, subsequent races can be higher!“
BOX: “Yeah, thanks, good effort on the market. We’ll verify collectively, in all probability a bit overbalanced all through defending the fronts. We will talk about later.“
What “overbalanced” and “defending the fronts” imply
The time period “overbalanced” refers to a automotive configuration the place the entrance grip is bigger than the rear grip, leading to a extra oversteering steadiness. This selection is intentionally made by groups on circuits like Suzuka, generally known as “front-limited.” This time period refers to tracks the place the entrance axle tires—resulting from quick corners and frequent path modifications—are probably the most confused. Due to this fact, to enhance race tempo, these are the tires that should be managed as a precedence.
Groups, to this finish, deliberately shift the automotive’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 splendid automotive steadiness, but it surely represents a compromise aimed toward tire administration, with the purpose 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, growing 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 selections made by his facet 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 accordance with the crew radio—did it not repay? The primary reply lies within the tire degradation throughout the GP, which was surprisingly decrease than anticipated (and in comparison with common requirements at this observe). Consequently, 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.
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 automotive’s drivability.
