Perfect Your Kart Setup
Whether you’re a competitive racer, kart parent, mechanic, or team manager, KartBalance helps you achieve optimal weight distribution and balanced corner weights for better handling and consistency on track.
A properly balanced kart turns the same left and right (unless you only turn left), responds predictably, and builds driver confidence. KartBalance helps you get there faster.

How It Works
• Weigh your kart using four bathroom scales (one per tire)
• Enter corner weights into the app
• Add and position weights on the visual chassis diagram
• Drag weights to see real-time center of gravity changes
• Find the best mounting location before drilling holes
Make setup changes virtually before making them permanent.
----

Why Weight Distribution Matters
Proper chassis balance is critical for competitive karting.
Too much front weight can cause understeer.
Too much rear weight can lead to oversteer.
Uneven left-to-right balance can make a kart unpredictable.
KartBalance takes the guesswork out of setup and helps you find the right balance faster, so you can focus on driving.
