cal tracks vs slapper bars

Caltracs have several importantant advantages:

1) They do not affect normal street driving - you don't even know they are there.

2) They can nearly eliminate spring wrap, alleviating the need for a pinion snubber and allow running as little as 2-3 deg neg. pinion angle.

3) They are easier to adjust for the desired effect. Little guesswork, just dial in the desired tension, if any.

4) They convert pinion-climbing torque to downforce on the front of the springs, creating a very solid "hook," no hop.
