Why you’d do it

  • Runs everywhere: club, regional, national
  • Your data and setup learning carries up the ladder
  • Masters/Heritage grids full of parents exactly like you

Why you might not

  • Top ends every 8–16 hours
  • Fuel is $100–150 a weekend
  • It’s fast enough to hurt

Things to think about

  • Track engine hours from day one
  • Buy the MyChron before the second set of tires

Your job as the parent

Race it yourself in Masters/Heritage, and wrench for both of you. Two karts is a real weekend.

This is my class. A year in I’ve learned the kart is only ever as fast as the driver’s worst corner.
