Buying a set of scales seems pretty expensive for periodic use. And trailering my car to a race shop somewhere to get a moment in time reading or pay for the shops time moving things around seems more expensive. Wondering if anyone rents this tool for a day or two?
if not, what are the hive’s thoughts on if this would be a reasonable business venture... buy a set myself and rent them out as discussed above? What is the lifespan of a good long acre set?

Good to know!
You can also DIY.
You can get a 660 lb capacity digital platform scale on eBay for about $40 USD.
These feature a remote control head/readout connected by a cable.
Cut 12x12x1/2" plywood to sit on top.
Get some large zip-loc bags, squirt a bit of your favorite personal lubricant inside each.
Evacuate the air, and place between tires and plywood on one side of the car to handle lateral thrust loads.
Label each control head (LF,RF,LR,RR), then group them together in a square, and take a picture of the weights with your cellphone.
Use Excel to fangle a spreadsheet that calculates total weight, front/rear/left/right percentages, crossweights, wedge,
etc. from the 4 values that you enter from the picture. (how do I attach a spreadsheet or a pdf to show an example?)
You can create graphs of roll stiffness, weight transfer, etc using Excel formulas and Macros.
Gives about 2500 lb capacity for under $200.
Not as easy as a commercial set of cornerweight scales, but a whole lot cheaper.
(Edit: Thx for printscreen tip)

I don't think you can. Link to Google Drive/Sheets may be the best bet.

Screenshot and it suddenly becomes a picture!
Scales are like engine hoists. The goal is not to own a set, the goal is to have a friend that does.

Welcome to the forum. Hope to see more of ya 'round here!
I've heard of clubs many years ago that did this, but nice to see the concept brought to the modern age.
