Corner weighting on the cheap

So I'm about that point where I'll need to corner weight my project. I can't seem to find a local shop with corner scale, so I'm looking into cheap GRM solutions.

I saw this setup on eBay, which is cheap enough, but I am a little doubtful of the precision of those scales.

Another option I saw, is this wheel load checker from Speedway. I have more confidence in this, but I can see this as being a pain to go to each wheel repetitively, while setting up the car.

No way am I spending four figures on a set of Longacres, and used shipping scales seem crazy expensive around here.

So any experiences, opinions, etc...

I've seen those scales used and they seem to be just fine. I'd calibrate all four with a common weight to be sure they're the same. The principle of operation makes sense. I've got no experience with the wheel load checker.

4 $10 bathroom scales from Wal Mart and a few chunks of scrap lumber will allow you to build a scale setup that uses the principles of leverage to get some accurate scales for not too much money... i haven't tried build this setup yet, but one day i will..

google found me this thread on another site. i'd make a couple of changes- add in some solid pivot points to keep the measurements consistent, but there's no reason why it wouldn't work and be consistent if things are set up consistently..

i've seen images online of people making things out of aluminum and steel instead of lumber, but this was the first one i found in a quick google search just now..

I bought a set of intercomp scales, complete with the rolling rack, for $350 used. Deals can be had.

I bought a set very similar to those off ebay maybe 6 years ago. They have worked very well for me. The scales need to all be set accurately around the value your car will put them to - I used a weight lifting set to calibrate mine. I found them to be very repeatable once set. One problem the particular set you pointed out will have is there are no wheels or roller bearings on the weight bearing pieces (Y) to allow them to move in and out under load so when you lower your car onto the pads, your suspension will not settle properly unless it has a solid axle front and rear or no suspension droop and solid bushings. This will affect your corner weights. Driving on and off them would solve this but I dont know how practical it would be to build or use such ramps...unlike "pressure plate" type scales - wherein the exact location of tire on the pad is of no importance - tire centering on these makes a difference in the weight read.

Yep. That's pretty much what I did. Went "IN" with a couple other locals on a used set. Generally I just need to go pick them up about 20 minutes away whenever I need them and keep them until the next guy needs them. Generally a month or two. My share was about $150.
