I have the Calmini AAL's and have cranked the front a bit. In doing a search trying to figure how high to go in the front I found two methods. One is to measure from the UCA to the bump stop which measures 3/4". The other method was to measure from the lower control arm pivot bolt to the ground and to subtract the distance from the steering stop bracket to the ground. The spec given is 1.8 to 1.95. I have 2.5" on both sides. My question is which steering stop bracket should I measure from? I measured from the the bottom front bracket is this right? Also which method is the best and most accurate? Thanks in advance.

You should use the bump stop spacing & adjust the t-bars to get it near what it's supposed to be (mfr should tell you...).
The second dimension you mention is supposed to get bigger with the UCA/T-bar lift; so the factory spec you mention no longer applies.
The real determinant is how much t-bar crank allows you to get proper caster/camber alignment numbers & I believe this occurs with ~1/2-3/4" UCA-bumpstop spacing for most/all UCA lifts available.
