I use this meter to determine how much force it takes to lift the rear of the chassis off the track. This is helpful in determining if there is enough downforce for the best traction off the line. Too much slows the car at top end and to little hurts ET. I find that the AW track gives less downforce than the MaxTrax due to thicker\higher rails I imagine. Gram meter

Back when I was racing organized road course, I had built a meter using a hall effect sensor to check down force. Sold it when I sold all my racing stuff 12 years ago. I saw a car somewhere that they built with adjustable traction magnets. I stored that idea away in the dark, dusty recessed of my somewhat normal mind. Rail heights and thicknesses are the issue with proxy racing. No way to get it dialed in, just close, somewhat. The main reason the "other guys" own so many of what is now call silly foams.

Hey Dave,that gauge is so old school cool and useful too! What scale of measurement does it use? (ie;) foot lbs. etc.

0-100 grams which works well for HO cars. Some of the neo magnet cars will exceed 100 grams. I bought that old gauge on e bay for a reasonable amount. You can have a small neo magnet that reads 3000 on a gauss meter but size matters with traction magnets and a big ceramic could have more downforce than a small neo so this tool is valuable. It helped me tune my inline stockers for Jeff's upcoming race, I think you will see that it made a difference.
