Used on 2013 Scion FRS. Utilized top hub position seeking max negative camber. For $30 bucks shipped I dialed out most of the annoying understeer this car has at the limit. This is my weekend car and I drive it very hard. The understeer was usually more pronounced once the rear tires warmed up, that is gone, too. I did not get an alignment done, just put the bolts in and drove the car, which worked fine. Great way to liven things up for cheap.
