Episode notes
Drive Beyond The Comfort Zone
- When the driver says the car handles perfectly but is not fast enough, push the driver to explore the car's limits by driving harder.
- Finding the car's behavior just beyond the limit exposes weaknesses to improve for more speed.
Gain Grip By Adjustments
- When you need more grip at a perfect balance, try adding downforce, softer springs or anti-roll bars, and experimenting with tire pressures.
- Lowering tire pressures gradually and observing lap times helps find the best grip before performance drops.
Confidence Beats Pure Grip
- Increasing tire pressures unexpectedly improved an intermediate driver's confidence at Laguna Seca by providing vehicle stability.
- Stability helped the driver push harder, even though physical grip was lower, showing confidence's effect on performance.
