9 times out of 10 all problems are caused because you missed your apex. In karting you need to be as precise as .5 inch. If you miss your apex by just 2-3 inches that translates to tenths of seconds. If you miss it by a foot your now half a second plus.
What is threshold breaking? Threshold braking is a driving technique that involves braking as hard as possible up to the point where the wheels are about to lock up, or reach the threshold of grip. This is important in racing because it allows the driver to maximize the amount of deceleration they can achieve while still maintaining control of the car. If the wheels lock up, the car will lose grip and may skid or spin out of control. By braking hard up to the threshold, the driver can slow the car down as much as possible without losing control. This is particularly important when entering a corner, as it allows the driver to carry as much speed as possible through the turn.
Practice makes perfect. Nobody talks about this enough but the reason why we practice goes a lot deeper mentally. Experienced drivers are performing techniques and skills that are basically in their sub concious. They have to hardly think about what there doing. Where a brand new driver is thinking heavily about every task that is required. If you want to go faster it starts with seat time. My suggestion. Focus on consistancy first, speed second.
Passing is the difference between getting to the front of the field or staying mid pack. Now I see a lot of crashing. Why? because drivers do not complete high percentage passes. I want you to think back and evaluate each pass clean or contact and evaluate it out of 100%. Were you right besides the driver? Did you stick only your nose in, Was it a late pass?
Look at the end of the day you are responsible for bringing home your kart in a race. Nobody cares that you crashed out trying to make a pass (including your team mates). So make passes that stick (high percentage). Get besides the driver, hold them to the outside and then steal their line. If you throw it in late, or just stick your nose in a little, guess what you really risk the chances of making a low percentage pass and will find yourself standing out on track with a DNF.
Having a driving coach that works with you or your child will make a world of difference. I have been coaching since 2006 and the amount of success I have seen with each driver is truly measurable. I think its also very important to find a good coach. Just because they can drive doesn't mean they know how to teach. You want a coach that can explain what the issue in in a way the child understands but more importantly teach them how to fix it and give them solutions. A coach is someone who always motivates them. A coach is someone who makes them feel like they understand where there driving ability is, and that they have a team mate (Coach) working alongside them. Good coaches that work with kids and drivers really have a knowledge about mindset and development and help kids improve in more aspects then just setting a fast lap. There is so much pressure on kids and that is just one example that can be worked on that drastically changes a course of weekend.
