Hi
Can't help you exactly..
But there's a good few people, me included, using these:-
The Bay of E > 'Postal Scales 200kg' - buy 4 of them for circa £120.
Mine are consistent to within 0.5kg (using a test weight of me..) across the 4.
Seems to be very similar to what other people find.
I found that making some timber platforms that sit next to the scales so I can roll the car back and forth helps too - for these or the pukka
stuff.

Did you try using yours in the same position as the professional ones? To do this properly you need a perfectly level surface. Garages are supposed to
have a slope to the garage door.
If you put a control weight across the scales (when the scales are in the same position) and they read the same the problem isn't the scales.
However, for the control weight I'd have three, one s little below expected weight, one around and one a little above. You can then plot of the
scales are linear.
(A long time ago I bought 8 bathroom analogue scales to do something similar, figuring none were accurate my plan was to work out not the weight, but
the defection from each other and minimise that. Still not done it)

No it wasn't done in the same environment, but on the basis I corner weight for equal front and they were perfect in my garage and 25kg out
across the front on the proper scales, and the car is only 470kg so it's a fair chunk of the total weight, I now have no faith in them.
I wasn't expecting perfection, but to simulate that kind of weight shift I'd need to turn a pushrod at least 2 turns, I'm fairly
confident it wasn't the floor that put it that far out.
I'm happy enough investing in a proper set it's just the dreaded vat that kills it on a new set.

Just a thought, there are weigh bridges in council tip venues, you might be able to 'trailer' your car there and get them both weighed,
then remove your car and do it again? or if they like you, they might let you drive your car onto their scales rather than a long winded on off on
off.

What would that achieve?
I'm not concerned with the total weight of the car, I already know that's where it needs to be

I'm curious how much it would take to change the weight by 25kg. I've never done it so don't actually know but can't imagine
it would be a lot. Now you've had your car setup, i'm curious what your scales would say if you checked them and if you reversed the car
and checked again. It would prove if the scales had an issue or if it was related to something else.

I always set the car up myself, I just borrowed a friend's intercomp ones hoping they would be somewhere near close to what I achieved at home
with the cheapo postal scales and they were nowhere near. Previously I was running with a team so used theirs - this is the first time I used the
cheapo ones, and it's doubtful I'll be using them again.
It's a substantial difference to be 25kg out on the front of my car, I have a good feel for this given how many times I've done it.
Appreciate people are just trying to help but can we stick to the reason I posted on the first place...if anyone has any proper corner scales for sale
let me know
