Corner weights
Am I right that I have to give a weight for all 4 corners for SVA? If so is it acceptable to weight the front end and the back end then halve both
results for the corner weights? I intend to get the weights done on a weighbridge.
Also I need to prove the age of my 1300 x flow. Does anyone know if the engine number list that gives year of manufacture that Burton Power have in
their catalogue is acceptable?

I got a recent letter from VOSA saying that my application won't go through until I supply design weights for front and back. So I just gave
just that and supplied a weight for the front axle and one for the back. Strictly speaking, halving one axles weight won't give the weight on
each corner due to the placement of things in the car, including the driver.

Guys please do a search!
Design weights have nothing to do with actual weight.
They are the maximum weight expected for each axle (front/rear) is likely to carry.
Your car might only weigh 550kg but your design weights might be 450KG per axle.
Like I said, do a search and you should find some values to put on your forms.

As Nitram says - design and actual are 2 very different weights. Do a search and also look at how the design weights are used in the brake efficiency
calculation. i cant remember the exact details now but you want the design weight to be at least 60% ish higher than the actual weight (dont forget
its nice to be able to carry a driver and passenger and a modicum of luggage - not to mention fuel etc), but you dont want it so high that you need
super huge brakes that are capable of stopping the full design weight.

Nitram, I should say that I have done exactly what you said it's just the beer wouldn't let me write it properly! I've a whole month
off work now you see so I'm up to day 9 on the beer. A liquid diet isn't that easy to keep up you know

I had a mate on a Guiness diet. 8 pints of Guiness a day. and no other foodstuffs.
20 years on he is still as rotund as ever. He declared the diet unworkable, but fun.

On the form we put design weights as 450kg front and rear, gross weight 900kg.
At SVA actual weights with all fluids but without driver was 308kg front and 304kg rear.
No problems at all.

As said the weights on the SVA form are "Gross Vehicle Weights". One for each axle and a total vehicle max (ignore the towing/third axle
one). The 2 axles combined, must equal or exceed the total. They also have to exceed the actual kerbside weight plus 68kg for each seat plus 7kg of
luggage for each seat (So Kerb weight +150kg for a 7even).
The brake test is done using this calculated vehicle weight based on what it reads on their scales.
The Fury is officially 500/500/1000 according to Fishers but this covers all engine possibilities.
