You can try to make a street car into an autocrosser or you can do a lot less work and make a race car into a great autocrosser
Very Interesting Mark, will have to keep an eye on this.

I've looked at these before and reading the reviews on Amazon and Summit make me think it's a roll of the dice.

I have a set of these. They are well made in USA. They work well and you can get them calibrated, repaired or just buy parts you need.

For starters, 70% of cost. Smaller so probably lighter. Come w/ a bag.

The Mittler scales Dan was referring to seem to be the same price as longacres. Same size.
I don't see that they come with a case either.
Their support and service is awesome.The case is extra. I don't have space for a case. They live on a shelf in the garage.

Ok, spending my tax refund. i ordered a set. The low reviews were from 3 yrs ago. Will report.

Some of the reviews say they are plastic, but Jegs clearly lists the material as aluminum.
Interesting. It would be nice to save $300...
They make some really good plastic these days.

A good friend of mine has a set that I've used, and I can tell you that they are definitely all metal.They make some really good plastic these days.

Scales arrived today so I put them to work. I made leveling pads and ramps for the front at the low end of the garage. The instructions said jack up the car and slide the pads under the wheels, so I did that for the back. Everything seemed to work well and the pads are just wide enough for the rears. I did not check the deeper levels of the screen(cross weight and several other things), next time. I did corner weight the front for balance and learned something new. Turning the front tires on the pads changed the weight a lot. I then realized that having both wheels pointed straight ahead was a min req. I found that one of my wheels was quite a bit off. Fixed that and then corner weighted the front.
The other nice thing is that they come in a metal box w/ wheels and a luggage type tow handle.
I will bring them to the Crows Tour in a week so you can ck them out, Ben.

Have not used the scales again, but Nationals had the same units at the Crows Tour and they were not very well received. Seems that they weighed a bit on the light side(even compared to mine) and that position on the pads altered the reading a bit more than was pleasing to some drivers.

I guess consistency is the main concern.
What would be interesting is if the next time you scaled your car, you weighed it, then swapped the scales left-to right and see if the weights come out the same.....
I doubt they're inconsistent due to the scales. All of the electronics should be able to give repeatable numbers, although different scales may give different results for the same weight (put a 50lb weight or something on all of them to check). My guess would be that a lot of the cost savings versus the Intercomp scales is in how they balance the load when its not exactly centered over the load cell. Depending on how the scales are assembled, turning the tires while on the scales might even add forces the load cell isn't expecting. Coming up with a method of getting the car on the scales consistently in the same location, and having specific scales at specific corners should help with this.
Hub stands tend to be a popular option for scales; they replace flexible, sticky tires with a metal framework which might help make the setup more consistent. Turn plates may also help this, by allowing the tire to turn (steering wise) freely. The downside of these two options is they're not cheap, but on the upside, they should make alignments very quick. The cheaper version of turn plates is a tile with grease between the tile and the scale.

Has anyone else had any luck with the Proform 67650 scales? Is the smaller pad size a problem?
For another $450, both the Intercomp SW500 and Longacre AccuSet have a standard 15x15x2.5 size pad. Seems like those would fit a lot better in the wide variety of levelers, racks, and ramps that are available.
