I started racing sprint karts about a year ago and now have 10-15 races under my belt. My performance is definitely improving, but one thing I struggle with is how much a car changes through the course of a long race.
I’m starting to get the hang of cold tires at the start of a run because I practice in those conditions every time I go on track. Once the tires warm up a bit around lap 5-10 I get in a groove and start making up some ground. However, at the end of a race is really when I struggle.
It seems like no matter what I set my tire pressures at, or how well I try to underdrive to save them for the end, the car becomes a handful in the later laps. I can’t seem to maintain the pace that the rest of the field has and I start falling like a rock.
I’ve changed setups, pressures, ride heights, etc, but I think it’s all coming down to the driver. My mechanic tells me that I seem to be over driving towards the end, but as you all know, it can be pretty difficult to slow down your hands and stay smooth with the throttle on hot tires with 3-4 laps to go.
What are some tips and tricks you guys use to adapt your driving to the changing tire conditions throughout a long race?
