Corner weighting a Cerb
Discussion
Call me a girlpants, but am I looking at an ideal means of corner weighting a Cerb, for £200

Just to give you an idea. Daemon tweaks cheapest corner weight for a Car is £1000.

Surely there must be a garage around somewhere that has this kit? I would be happy to pay someone to setup the geo and corner weight the car. Must work out cheaper and easier than doing it yourself?
If there is no garage that does it could we all chip in (those that want too) and get the TVRCC to buy it so we could all use it? Just a throw away idea but if the kit is really expensive it might be worth thinking about?

It'll only work if it doesn't add the 4 weights together. Ottherwise you'll just get a total mass of the vehicle.
You could just plug each one in at once.
I had mine done and it's not just the weight of the car it's the loading. The scales need to be set up level and the car rolled onto the scales so that there is no load applied through the suspension (i.e. if you were to jack it up and lower it onto the scales).
Mine cost me £100.

Where did you have yours done Matt?You could just plug each one in at once.

'The point' of this post is a small dot in the distance to you. If there is no garage that does it could we all chip in (those that want too) and get the TVRCC to buy it so we could all use it? Just a throw away idea but if the kit is really expensive it might be worth thinking about?
Seriously, I'm a bit of a nutter. I have a four wheel tracking device that I've refubished from a pile of junk, modified/remade all its stainless steel arms to fit the Cerb 18" spider and see round the low part of the bodywork on a cerb. I've spent about a month working out how to calibrate it and get repeatable results where measuring how square the corner of my garage is.
Having done that, its now sitting a a custom made shelf on the wall, and hasn't been used on the car yet.
I tell ya, you would need to be in your car and driving fast to have any hope of getting to the dot after posting that above.

It does add the four weights together, but I'm also reliably informed it gives you polar coordinates to a CofG. Its meant to be put at each corner of a tank full of somat. The point of the CofG output is that centring the load is important to haulers of large loads.You could just plug each one in at once.

Whether it gives more than that I don't know. What I do know is if thats right and it gives you that weight and a CofG I rekon I can back compute the rest.

Real 'old skool' garage; single seater race cars, exotica etc, but you had to crawl over lathes, milling machines etc. to get through the workshop. Perfect!

The problem with these is that as you say, they are designed to be sat under 4 corners of an object. To corner weight the car you need 4 separate platforms, one under each wheel. How would you physically use them? How would you create a platform for each wheel, with a single load sensor that would be accurate? (says the man who has a set of corner weight scales 
)
)Unless you're planning to ballast the car or move components around to get the weight distribution you want, what are you hoping to achieve by the corner weighting? The weight distribution is close enough to symmetrical that the ideal setup is with the spring seats set equally on both sides.
If you insist on corner weighting it then you can spend as much or as little as you want - the setup I use cost me under £20. But it's something that I regard as a total waste of time for road use and a waste of time for the vast majority of people on the track.

It started as a need to have my car weighed for the Sprint Championship, and has since moved on to an idea to see what effect corner weighting has.
I like knowing how to do things, and I'm now looking to learn about the car and how to set it up properly, in my eyes, what I'd like to do is to have a full set of figures as a baseline as close to 'perfect' as possible then I can learn the effect of changes that I make.
Without putting the car on a set of pads in the first place there is no way of knowing what the weight distribution is like on my car, I know the weight distribution of another Cerb' but that can't be applied to mine as they all vary.

Feel like renting them out Andy?)Tim
I'm reluctant for them to leave the workshop (unless with me to a circuit) due to their cost and (huge) weight. And I'm pretty busy with a car almost permanently in the workshop, so renting them out in situ is a bit of a pain for a relatively small payback.
If I had more space then I'd happily rent out time on them here.
If you're really stuck them PM me
