Load transfer changes tire loads, not total vehicle weight

The four contact patches
A race car interacts with the track through four relatively small tire contact patches. Every braking, accelerating, and cornering force ultimately passes through them. The driver does not create grip by moving the steering wheel or pressing a pedal; the driver requests forces that the tires may or may not be able to produce. Tire compound, temperature, pressure, track surface, and vertical load all influence the result.
Load transfer
During braking, load transfers toward the front axle; under acceleration, toward the rear; in a corner, toward the outside tires. This is dynamic load transfer, not a literal movement of the car’s total mass. Greater load on a tire generally increases its absolute grip but usually less than proportionally, so large load transfers can reduce the sum of available grip. Smooth transitions make the car easier to control.
Mechanical and aerodynamic grip
Mechanical grip comes from the tires, suspension, surface, and loading. Aerodynamic downforce increases vertical tire load with speed, usually making high-speed corners different from low-speed corners. A GT3 car may tolerate a larger steering or braking demand at speed, but downforce decreases as the car slows. Never assume that a technique effective in a fast bend will work identically in a hairpin.
Driving application
Approach every corner with a clear sequence: brake while the car is stable, progressively introduce steering, balance the car near the apex, and progressively unwind the wheel while accelerating. Use a repeatable setup and consistent tire conditions before judging whether a handling problem is driver-induced or mechanical.
Drive five laps at a comfortable pace and focus exclusively on smooth transitions between braking, steering, and throttle. Review whether the car pitches or changes direction abruptly. Smoothness is not slowness: it is precise control of the rate at which tire forces change.
