Go Kart Science

According to the Woodbridge Cart Club target weight distribution for go-karts are:
43% Front Weight
57% Rear Weight
50%/50% Left/Right Weight

Are these the ideal ratios?

Update:

I see that wildkart and dinardokarting suggest:

KF3:
44.4% Front Weight
55.6% Rear Weight

KF1/KF2:
43.3% Front Weight
56.7% Rear Weight

KZ:
43.5% Front Weight
56.5% Rear Weight

Similar to Woodbridge’s ratios.

kartpedia has these as a starting point:

42% Front Weight
58% Rear Weight
