Yes they do work and you will get more postive caster. If you installed them like the instructions in the package they might not help you much. The Moog intention of the bushings are for rusty cars that have sagging frames that bend inward over time. The "trick" is to install them like this diagram below and ignore the Moog instructions. The arrows will be pointing opposite directions front bushing to rear bushing. First make sure you set the ride height first to what you want. Factory manual alignment specs are no good for radial tires, they only work if you use bias-ply tires. For Radial tires, Camber -.50 to 0 degrees, Caster as much positive as you can get up to 3 degrees and toe in 1/16th to 1/8th inch. Car runs down the road straight as an arrow now. You will be limited to what you can do with stock A arm bushings, but if you have the Moog off set A arm bushing you can tweek it a little more.
