KIPAAdjustable Magnetic Gauge Tool Camber Castor Strut Wheel Alignment Tool For Truck Car

There is no way to calibrate it to zero to begin with, the adjustment knob is there and works but there is no way to put it on a known flat surface because both the magnet and the adjustment knob itself is in the way, AND even if you did manage to zero it, the readings are all inconsistent. I placed it on the rotor and turned it to level it out according to the small bubble level, i received a reading of .5 negative camber, i took it off and checked it again, i received a reading of 1 positive.

You can spend a long time to get untrustworthy results. Instructions are useless and show a complete lack of understanding of this tool and the process. After figuring out how to calibrate without instructions it is easily knocked out of calibration as the adjusting screw has no jam nut. Once you have it calibrated it is slow to respond and inconsistent. I bought a cheapy magnetic digital meter and it's 10x better than this. I only use this for front camber adjustment.FYI, I do the alignment with the rotors bolted down and the rotor sitting at ride height on stacked wood with 2 poly cutting boards (w/silicone sprayed in between them ) in between the wood.

There isn’t much complicated about this tool and I can’t n imagine the more expensive ones are any better. It’s relatively easy to calibrate with a large level and easy to use on the car. Using it with toe-in plates I was easily able to check and align my old car.

This thing sucks, it is not accurate at all. I only used it to try to get both sides matching in the same angle. But good luck trying to read the actual angle of where you want it to be.

Great for interim camber adjustment before you get to the alignment shop after installing new struts or ball joints. If you don't have a flat surface you can stick it to the brake disc and raise up the wheel - less hub until the two lower ball joints are at the same height off the ground.
