if the car is leaning over a bit when weighing 1 axle then the lower axle will take a bit more of the total weight than when level. Tip it up one end
at a time and both axles will seem to weigh a bit more than they should.

You dont put the actual weights on the SVA form - you need the design weights. These include allowances for passengers and luggage.
My Tiger Super 6 was actually about 660kg (lardy i know) but the design weights were Axle 1 - 450kg, Axle 2 - 500kg. Total 950kg. If you are building
a se7en then these will be around right for a car engined version

not sure if you are thick but that is a mere 3 %.
How accurate are the scales?
And how exactly was it measured?
Regardless of whether the wieghts add up or not, those are not t he oens you put on the SVA form.
The SVA form requires fully laden with some extra and is used for brake efficiency testing.
I don't have details at hand but recall something llike:
400 kg rear
350 kg front.
(f27 with crosslfow; you could put down about 50 kg ish less for a girlie BEC)

The SVA form (Q15) doesn't want the actual weight of the vehicle. Its design weight they want which is the max loaded weight for each axle. Most
put F 500kg, R 500kg, Gross 1000kg. Train 0
Braking performance will be tested and calculated from the weight readings taken at the test itself.
edit...need to type faster
