I'm loving reading this kind of detail! Thank you Rob and Ron for having most of this discussion 'publicly'.
I do have a question about the C6 spindle. I wasn't aware that the C6 ran that much caster. Can you explain a bit about the effect of running that much caster, or perhaps asked different, if you run less caster with the C6 spindle, what would the effect be?
My setup uses that spindle, but I've been told to target 6.5 - 7.0* of caster, and my recent alignment check shows 6.8* and 6.2* (I haven't had it aligned fully yet, but that is with camber dead on at the moment). While I realize my setup is different, it supposedly uses pretty close to C6 geometry points.
Keep the techie stuff coming! I'm learning from all of this too!
