Just wondering if anyone has 4 corner scales or know where some are available to use cheap. I called PAS and they do a full race balance and alignment for about a grand. I'm sure they do a great job but a little more than I need, just looking for a decent shade tree balance.

I know someone in the club has them.  If there are enough interested people
maybe we should put together a corner weighting party.

Several of us use Courtney Cormier. He is a National Champion autocrosser, autocross set-up guru, and head mechanic at Richmond MINI. He does a great job at a reasonable price. I sent you a PM with his email address.

Thanks David, I'll contact him and see. That also might be more than I need. I like the idea of a corner balance party though, it would be cool to hang and learn while others are doing their cars. Many hands would make light work for something like that too. It seems like it could be time consuming though, not sure how many cars can get done in a day.

The corner weight "party" is a great idea.  If it comes together I have a M3 that needs help.

I have scales, but basically zero time in the near future.  I'm happy to donate the scales if someone I know takes responsibility for them.  They're not cheap and they're far from bulletproof - I dropped one and it cost me $250 to replace the sensor.

Alternatively, if we do this in the Spring (April?), I should have some time and the space to host.

I'm in no hurry, need to sort a few things so whenever you get to it, I'm in! Too cold to be hanging around outside now anyway.

Yeah, I'm down to host something in the spring.  I'd guess we could do up to 3 cars pretty easily.  If I get a lift in by then, it'll go oven faster.

Seems like it would go faster if we just had ramps. Drive your car on, get the weights, get off and go make your adjustments and come back while others are getting their weights. Unless someone has the ability to adjust as it sits, too much time would be spent tweaking and going up and down.

I thought the going up and down part was half the fun.   Grin

This is a good point.  Maybe someone will build me some ramps Smiley  Hopefully it dries out and warms up soon so I can get the garage wrapped up.

give me the dimensions of your scales and I'll figure something out.

The scale pads are ~2 5/8" tall with a 15"x15" footprint.  I have a set of wood roll-offs for it, but you still need to get the car in place, jack it up, put the roll-offs under the wheels, and position the scales before you can use it.  I like the idea of ramps a lot.  I guess if it was possible to drive over the rear set of ramps and onto the front set, we could crank out a bunch of cars pretty quickly.

Tidewater Sports Car Club had a couple corner weighting sessions at Tidewater Community College's auto center a few years ago that were really cool.  Wasn't so much about corner-weighting everyone's cars as teaching us how to do it properly.  Started with a 90 minute classroom session covering race car dynamics and why corner balancing is important, and then we corner-balanced two cars for a demo using the club scales.  Maybe y'all could do something similar?  (Shoot, maybe we should do it again at TSCC, it's been a few years, lol)  We did it at TCC because two of the profs were active in our club at the time and did it for us for free, but it could really be done anywhere.

I realize this thread is almost a year old, but I didn't want to start a duplicate posting regarding car scales.

Any chance of getting something set up at an autocross or test and tune for anyone that wants to know their weigh balance this season. I for one would be interested and if a modest fee was charged for time and "wear and tear" I don't think anyone would mind too much.

Yea, I'd be in for that! I've never had my car on a scale.

I'm interested as well in getting mine up on the scales as well. Maybe early before registration opens one autocross? (Hopefully May since I'll miss this month's event Nascar! Haha )

I could bring the scales to the Practice Autocross in May.  It would give you total weight and rough balance.  Highly dependent on how flat and level an area there is to set them up.

Wow its been a year already, where'd the time go!? I'm still willing to build some ramps for this. Should be easy just stacked and staggered plywood about 20" long overall and as wide as the scale,  1/2" sheets staggered every 4" going up to the scale.

If we set up a station to pull cars up to, the rear scales and ramps can be slid out, pull car up to front scales and align them, slid in rear scales and ramps, weigh car, roll off, slide out rear scales, move car, rinse, repeat. Of course like you said, finding a flat level surface is the hard part.

I was talking with Marc last year and what he did to get a level playing surface was to get some floor tiles and stack them till he had each corner level with each other. Floor tiles are about 1/8" thick so getting something pretty close to level wont be to difficult.

SCCA uses two 10" aluminum channels between the front and rear scales on each side. The channels slide inside each other and are marked so you can set the scales to match the wheelbase of the car. If when had 4 ramps and the channels you can run a lot of cars across the scales. Like Justin said we need to find level ground but it should be good enough to an idea of where you are at.

A laser level and a ruler and I think we got it all sorted out. I can get the floor tiles and give them who ever has the scales next autocross.
