Proving vehicle weight for MOT test?

[artois7]

I wasn't really sure where to post this, feel free to move if there is a more suitable subforum.

I recently took my 309 gti in for an MOT, and because the mot tester didn't have an official vehicle weight, he used the gross / maximum weight in the vin plate, which is 1350kg compared to the cars actual weight of around 980kg.

That extra 40% is a huge factor in a brake efficiency test. The problem I have is how to prove this? My v5 doesn't list a kerb weight, and I don't have an owners manual. I assume they wouldn't accept a random car websites quotes as they could have easily just googled this fit themselves.

Any ideas how I can get an 'official' kerb weight that would satisfy the MOT tester, short of finding a weighbridge?

I was wondering that - surely that's the whole point in the brake test, if it can't cope at max weight then they're not good enough anyway.

With an extra 400kg in the car, there would be a lot more force on the brakes so it would behave differently.

I got a scan of the owners manual which shows the kerb weight at 930kg, this was accepted for the test.
