Weight
 

I'm just about to fill in my IVA form but not sure what weights shall I put down on my IVA form?

what has anyone else done for this?

I put down 450 kg, 450 kg and 900 kg gross. This is the same as on my manufactures plate. The examiner said that was ok.

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:D

Thanks for the replies

I will fill out the forms hopefully this weekend

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!

i put the same as thats in the book and i pased fine even with a 35l fuel tank

axle 1=450kg
axle 2=450kg
total = 900kg

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
