Rego has my car down as 1418kg, but I found that an R33 4 door is 1390kg and Coupe is 1370kg (manual). 1410kg & 1390kg (auto).
As my car was Auto but converted to manual in Japan, I queried this with them and was told, if I got a Weighbridge Receipt (for $25.ish from the Tip in Mitchell,) then they could change it. (this was at least a year ago.)
But I never did as it would still be in the same pricing bracket anyway.
The other thing is Shannons have my car down as being a HR33 instead of ECR33.
According to them they don't have ECR33 in the Database?
