I am having difficulty figuring out the best way to set kingpin length on my CRC gen-xl. I know that both the manual and Mark Payne's blog mention that while the front end is off the car, you just thread the kingpin in until there is a slight amount of preload and the spring just touches the e-clip the whole way around.

However, I am also familiar with the CRC driver's .404" is god method. This method appeals to my precise nature (more so than "screw in until just a slight amount of preload"). But, given the nature of CRC parts (inaccuracies, imperfections, etc), you essentially never get two front springs of equal length. Thus, the .404" method is no longer valid.

What I have been trying to do is set the kingpins at a certain length equal on both sides, and then placing the complete car (with electronics, battery, etc) on a level surface. I then adjust kingpin length until droop looks equal on both sides of the car. This method seems to work ok, but I really dislike the imprecision of it all. My eye certainly can't see a difference that could potentially make for a poorly handling car.

Anybody have any recommendations? Am I overthinking all of this? Thanks for any and all help, it is much appreciated.
