Hi all
I'm looking for a lo cost way of setting my car up with me in the driver seat.
Has anyone got a cheap solution they could talk me through.
Thanks
Lee
You mean beside sets of bathroom scales and a mate to read them.
It really depends on the weight of the car and you in it as most scales will only go up to 150 Kg each, so if combination is over 600 Kg then you will
want 8 scales!
There must be a way using water pressure and areas of pistons under each tyre, but would be expensive to get the pistons.
So find somewhere that will do it for you I would suggest.

If you do a search there's a few ideas explained already. I think one of them was to replace your weight with a bag of sand (or two!) in th drivers seat and to have two sets of scales per wheel, bridged with a piece of wood and go from there.
What sort of money would you consider a "cheap option"? - I know that free is cheap etc, but wondered whether you had a budget in mind that you would be willing to pay to get your car to handle the way it should...
4 x homebase scales for me as its a BEC
Okay accuracy may be rubbish for weight, however you are looking fpr comparison so load them and zero at you target weight.
You then need somewhere really flat, I laid out boards where the wheels/scales would stand and packed under with sand until perfect.
The weight transfer is quite amazing when you mate sits in the car and moves about!!!
Another way is to use the power of levers, make something with a pivot near the wheel and a bracket so you can pick up the wheels in turn, then work
your way around measuring the load to pick each wheel up.
If you don't mind the time it takes you can get by with one set of scales and three blocks of the same height. Much longer but much cheapness.
I'm not normally one for singing someones praises that I haven't dealt with, BUT I beleive Procomp offer a reasonably priced service
(onsidering the length of time it takes) I spent close on a day doing mine with bathroom scales.

axle stand about hub height , mark the position equally from all 4 wheels .
long bar about 1 metre long , insert into hub , using axle stand as pivot , lift wheel (in the same place each time) and 'feel' the weight
. we did the initial setup on darrians like this .
you can also build your own corner weight gauge with some box section and a pressure gauge , a la staniforth .

Me and my mate bought 8 sets of bathroom scales from Tesco at about £2.50 each. Put two under each wheel - it works fine.
I intend making something to lift one wheel at a time and have a 250kg capacity load cell from some industrial scales, but havent yet worked out how
to get an output I can display on a meter from it.

Load cell will possible have a 4-20 millamp range of use you muiltimeter and a +28v Supply and you will get an answer in 4-20mA then use y=mx+c to
convert into KG's (you will need to know the full range of the sensor)
or aleast know weights .
