Need help with UCA bushings

lawndart, IMHO I would only use these offset bushings if your vehicle has an issue with negative camber or caster. Could be helpful for a vehicle that has been wrecked or altered (lowered, etc.) and won't come into alignment specs.

In past experience, if installed when not really necessary, specs could be too far positive causing more issues.

The deal is, the factory called for negative caster and positive camber. But those specs were for narrow bias-plies on crowned roads. With modern tires you want positive caster and negative camber -- that's the idea behind these bushings. A lot of the "G machine" types will tell you they like 4 to 5 degrees positive caster on the street.

Thanks for clearing up the question of the washers. It seems to have helped a lot of people.
