Weight

[snapper]

The axle weights are the max fully loaded that the car is designed to take not the actual as measured
Weights include full fuel tank 25 to 35Kg
Driver and passenger 75Kg each
Luggage 25Kg each

Design weights for IVA are used to find if the build is within design limits and also to work out the brake bias when tested on the brake rollers
As axle weights are measured on the rollers and one axle is on the hard standing there is a slight lever effect
