yep they are the numbers I used.... BUT the way I built mine sent my rear axle weight over but being the manufacturer you can just write it down on a piece of paper informing them /him of a specification change

I did the same. My MX5 build is weighing in at ~620kg without fuel so if there is more than 450 over the back something is up!

It does not make sense the weights being the same,if you put both axles at the same weight then the DGW is say 900 kg one axle would possibly be overloaded ie the front one.

450 / 450 / 900 worked for me.

After thinking about it,its probably good numbers and maybe a little high for the rear.

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
