Yes, that is right. They tilt out the bottom edge of the knuckle/spindle. The ones from Mancini racing are said to result in 2 degrees of negative camber. They look to me to be around
3/16" thick. That is more that we need, so I'm thinking of using thinner ones, yet still grade 8 for strength. I figure if 3/16" is worth 2 degrees, the 1/8" ones I can get would result in 1.3 degrees. Since outward adjustment of the front alignment cams to gain caster also results in a positive gain in camber, I think it should work.
