Cornerweight, for real

Last attempt to weight my car using bathroom scales failed miserably, so I took a trip to Speedlab Racing and got help so set up the corner balance properly using their professional equipment.

Without driver the car weighted 590kg, race ready with a bit more than half tank of fuel.

After some adjustments a perfect 50% cross weight was achieved.

With driver and helmet, without nose-cone and bonnet.

It was also fun to take a look at their awesome Corvette-based race car! It is really something extra and worth a trip on its own. Take a look at their home page!

DIY Cornerweight

I've been looking for corner weight scales for rent at a reasonable price for some time now without success.

At the local Biltema store 130 kg analogue bathroom scales was only €5 each, so I bought a complete corner weight rig consisting of 8 scales for less than what it would cost me to rent racing scales a few hours. Not as accurate of course, but I thought that hopefully they was accurate enough and I can do it any time I want.

Well, they weren't.

When I was standing on a scale, my body weight shifted +/- 10 kg depending on if I was standing on my toes or on my heels.

First I tried with a piece of plywood to even out the weight, but it did not help much. I got the same readings without it and easier to handle.

I repeated the measurements multiple times and the readings was a bit more consistent than I expected, within 10-15 kg. Still not good, but maybe enough for a very rough corner weight adjustment.

Anyway I don't trust them, even for my own body weight.
