Want something inexpensive and totally portable to check corner weights? Here’s a unique item–I’m not even sure what to call it. That little protusion on the short end of the bar fits under the top rim of a wheel, then all you do is lift that corner of the kart (by pressing down on the long end of the handle) to get a reading on the gauge for that corner. The gauge does NOT read weight directly (though maybe it could be calibrated to do so)–it simply measures the hydraulic pressure required to just lift the wheel off the ground. So you get a reading for each corner, and then simply convert to percentages (which is what you’d do anyway). This is NOT going to tell you the actual total kart weight, but if what you want is an inexpensive, accurate, and extremely portable way to check corner weights, this is ideal. SOLD.
