What is this product good for? Here you do not pay for the exact tool. It will not replace alignment. However, the curvature is narrow enough on both sides that it can be balanced. Left and right within 0.2 degrees. My 2014 Challenger needed camber bushings and bolts to keep it from eating tires. Did this job yesterday and saved $200 in labor by wiring it myself. I also have a 99 F250 Superduty 2WD and that allows me to change bushings at home instead of paying the shop an hourly rate. Nice little tool to get you closer before the store makes it perfect.
