4 matched scales, good for set up. No they are not high tech digital, but they are only $20 (for all 4) and if you adjust them all to match before you put the kart on them, with something in the same weight range as what each corner of the car would weigh these are quite accurate.
Call my cell phone to schedule pick up in Bel Air, MD 918 360-3908.
If I have to ship them then I will package them and take the box to UPS for freight charges and communicate the new total to you. You send me a money order for the total amount and then I will ship them to you.
Thanks
