corner balancing, thinking of buying scales

I have always wanted to corner balance my car, but never wanted to pay the money for someone to do it. I came across a Longacre Accuset 2 for sale (asking $700). It is not the new one with the tablet display. I was thinking a bit high for cost, but it might be fun to have as i have a couple of cars with coilovers.

Any have one of these units? Worth it to get? Thanks

I have access to an Intercomp EZ Weigh setup which looks very similar. You just need something with accurate weights w/ cross weight %. This isn't something you will use but a few times, most likely. The trick is to find other buddies who also would like to use it and will buy in on the tool. 99.9% of its time it takes up space in your garage.

The other option is to find an actual road race shop that will do a setup on your car. For instance, the guys at Sick Sideways in Sebring, FL will do a setup (alignment with corner balance) for $400. They are an MX-5 Cup championship team and know a thing or two about alignment. But then again... what's the perfect setup for a FFR roadster???

Like I said, find some buddies that want to use it too... It's nice to have and you only need to buy it once.

I think corner weighting is worth the time and effort on every car.

$700 is not a bad deal for Longacre stuff. I would buy it. Use it a couple of times. And then sell it for $700.

I don't like the Chinese knock off stuff, and won't pay anything for it.

A cheaper option would be Ruggles Scales. Not as fancy, but just as accurate.

I agree with Bob. Also I'm in Southport, NC and if you are close enough (SC) I'd be willing to 'rent' it from you for setting up my car this winter.

Just saying before you invest 700$:

Donít forget that scales need to be level to make any kind of corner weight measurement. 1/4 inch on a 500lbs/in suspension spring will read 100lbs off.

You cannot just put them on a garage floor and expect good measurement.

2X what Totem says

Set up 4 pads on your garage floor that are level to better than 1/4". Also, recommend taping the pads to the floor, since you'll need to be lifting the car multiple times to adjust the coil-overs. Cross-weighting really helps.

If you are going racing, then it could be worth it. We have about 45 members in our club, the club owns a really nice set of scales with digital readout. Once a year we have a garage party, any member can scale their car and make adjustments. We have two or three do so, mostly it's the same guys, or a new build. I don't remember one time, that the weights where off so much that it was affecting the handling of the car on the streets. My car had about 900 miles on it when I did mine. Ran it on the scales, turned off the engine and looked over at Keith who was reading the scales, he looked up and said "you're done, back it off". If you measure the spring length on the fronts equal, then the backs equal, side to side, you will be close enough for any street driving. My cross weights where off 1.5%.

For as little as i drive (street ony) I realize it isnt really needed. For me much of what we do on these cars is more about the learning experience than anything else. I learned so much doing my build. I set up the suspension myself and learned a ton about alignment. Scales would be an extension of that. I justify a lot of stuff as "continuing education"!!

I say go for it. You have several cars to use it on so why not. Also buy some exercise weights or bags of river stone (at HD) and a few tool bags. Put about 50# in each bag so you can throw them in the driver's seat prior to weighing.

I would disagree with that. If you're racing, you need to spend the time to get the balance as near perfect as you can get it. Even to the point of moving things around. It makes a huge difference on the race track, where you're driving on the edge lap after lap.

On a street car, I still believe it's an important step. Although getting it dialed in to the last ounce is not as important. Driving down the highway at 55mph, you won't notice any difference at all. BUT.... what happens when you need to make an emergency avoidance maneuver? If properly balanced, your transient response and braking control will be significantly improved. It can make the difference between a near miss and a crash.

We spend a lot of time tuning the engine for every last bit of HP, and every bit of drivability we can get. We get OCD about things like fan control, what oil to use, and what spark plugs work best. But many of us don't take the time and make the effort to properly tune the suspension and chassis.

Power is nothing without control.

I’d rent them from you for $100 and pay shipping both ways if is reasonable! Of course I would have them a few weeks but it might help you make a decision . still probably less than paying someone to do it!

I'd be interested in going in on a set with others. I'm in South Carolina also. I live near Myrtle Beach in the Murrells Inlet area.
