alvin, I don't think that it would give ant anti-dive or anti squat. If you look at the cars that you'd normally think of having aint-dive/anti-squat, like a touring car or an offroad car, the lower arm is moving and thats where you adjust anti-dive/squat settings. On a 12th scale the lower arm isn't moving at all just the upper arm is moving, so i don't feel that there would be any anti-dive/squat on a 12th scale suspension. All reactive caster blocks do is give you less caster entering the corner and more caster coming out of it, say 2.5-3 going in and maybe 4 coming out of the corner. Thats just my feelings on this, but see what other people have to say.
