OK, so a sanity check and a few questions.

Sanity check; doing some basic trig to figure out how much negative camber my '74 2.0 has, I have calculated it at -2.8 degrees. That translates into 170 minutes of angle. The factory recommended setting is -30 minutes. So that leaves 140 minutes of correction. Each 1mm of shim correlates to 10 minutes of angle adjustment... so 14mm of shims, that seems like way too much. Do my calculations make sense?

Questions; to what extent would fresh springs remove negative camber? My springs are factory original and I would guess have lost some "spring" over the years. I plan on replacing the springs before I tackle the shims. Since the car will mostly be a street/pseudo track day car, stiffer springs are going on. However, the stiffer springs, 165 or 180lb variety are somewhat shorter, right? So, how does that play into the equation? And since it is to be a street/track toy, how much camber is recommended?

Advice is greatly appreciated.
