Go-kart axles play a crucial role in the setup and performance of a go-kart. Since go-karts lack suspension, the axle becomes essential for handling and power distribution to the rear wheels. Let’s delve into the details:

1. Medium (Neutral) Axles:

   • Usage: Around 75% of the time, go-karts use medium or neutral axles.
   • Performance: These axles perform well overall, aiding the go-kart in corner exits by providing effective power delivery.
   • Adaptability: They respond well to changes in track conditions.
   • Recommendation: When in doubt, revert to the neutral axle—it’s a safe bet.

2. Soft Axles:

   • Characteristics: Softer than medium axles.
   • Braking Stability: Soft axles enhance braking stability during corner entry. The chassis feels grounded and slightly squats during braking.
   • Entry Speed: They allow higher entry speed into corners due to increased grip.
   • Trade-Off: However, soft axles sacrifice spring-off ability at the center of the corner.
   • Use Case: Ideal for confident braking and aggressive corner charging.

3. Hard Axles:

   • Stiffness: Hard axles are stiffer than medium and soft axles.
   • Cornering: They maintain stability during cornering but may compromise overall grip.
   • Specific Applications: Hard axles suit specific track conditions or driving styles.
   • Experimentation: Drivers often experiment with hard axles to fine-tune their kart setup.

Remember, the choice of axle type depends on personal preference, driving style, and track conditions. Axles significantly impact how your go-kart handles, so finding the right balance is essential for optimal performance on the track!
