JOINMost drivers learn racing lines in low-grip conditions. The surface is consistent, the kart feels predictable, and textbook lines work well.
But grip never stays constant.
As rubber builds and temperatures rise, the racing line evolves. Drivers who fail to adapt are often the ones wondering why their lap times suddenly stop improving.
1. Grip Changes the Ideal Line
In low grip, wider momentum-based lines help the kart rotate and maintain speed. As grip increases, minimum corner speed rises and the kart needs less forced rotation.
With enough grip, a tighter line can hold the same apex speed while covering less distance. Higher-power categories benefit most from this shift, while lower-power classes often still rely on momentum.
Recognising when the line should tighten is subtle. It’s something you feel before you can see it — and that timing is something we break down in detail inside our courses.

Grip changes the ideal line. You need to recognise the moment and make the transition repeatable.

2. Too Much Grip
Grip doesn’t increase performance forever. Too much grip can cause binding, stiffness or a loss of rotation mid-corner. In very hot conditions, tyres can even become “grip slippery,” sliding on the rubber layer before suddenly biting again.
Knowing how to recognise transitions – and how to adapt your driving before lap time drops – is one of the most important skills we teach inside our courses.
Conclusion
Racing lines are not fixed shapes. They evolve with grip, temperature and compound. Drivers who understand why the line changes – and adjust early – gain consistency and speed. The rest keep driving yesterday’s line on today’s track.
