1. What is Go-Kart Cross Weight?

Cross weight percentage is a critical measurement in go-kart setup that indicates the diagonal weight distribution between the right-front (RF) and left-rear (LR) corners of the kart. It affects the kart's handling characteristics and cornering performance.

2. How Does the Calculator Work?

The calculator uses the cross weight formula:

\[ \text{Cross %} = \frac{(RF + LR)}{\text{Total}} \times 100 \]

Where:

\( RF \) — Right-front weight measurement (kg)
\( LR \) — Left-rear weight measurement (kg)
\( Total \) — Total weight of the kart (kg)

Explanation: The formula calculates the percentage of total weight distributed diagonally across the kart, which influences how the kart handles during cornering.

3. Importance of Cross Weight Calculation

Details: Proper cross weight distribution is essential for balanced handling. Too much cross can make the kart loose, while too little can make it push. Optimal cross percentage varies based on track conditions and driving style.

4. Using the Calculator

Tips: Enter all weight measurements in kilograms. Ensure accurate measurements by using proper scales and having the driver in the kart with all racing equipment. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the ideal cross weight percentage?
A: Ideal cross weight typically ranges between 52-58%, but varies based on track conditions, kart setup, and driver preference.

Q2: How does cross weight affect handling?
A: Higher cross weight generally increases cornering grip but can make the kart looser. Lower cross weight reduces grip but can make the kart more stable.

Q3: When should I adjust cross weight?
A: Adjust cross weight when you need to change the kart's handling balance - typically when experiencing oversteer or understeer issues.

Q4: How do I measure kart weights accurately?
A: Use individual corner scales with the driver in position, wearing all racing gear. Ensure the kart is on a level surface.

Q5: Can cross weight compensate for track conditions?
A: Yes, cross weight adjustments can help adapt to different track surfaces and conditions, but should be part of a comprehensive setup approach.
