C6 Suspension Questions
Okay. I spent too much time with a shock guy yesterday and my brain is full, but even with that I'm full of more questions.
C6 motion ratios? Anybody know them? My basic understanding is it's the ratio of wheel movement to shock travel.
C6 unsprung weight? Since I haven't touched my springs, hopefully somebody else has put a stock corner on a scale front and rear?
C6 spring rates? Base C6, C6 Z51, and C6 Z06. I couldn't find these anywhere -- I did dig up the C5 Z (526/714), C5 T1 (582/793), and Hyperco rates (street 565/765, track 625/850).
Interesting find from the shock dyno was that the stock C6 Z51 rear shock has more compression and rebound than the front! And the C5 Koni 3013 has a compression curve very similar to the C6 Z51 front shock, but the adjuster can get you _a lot_ more rebound.
Anybody have pictures of how the Motons, Konis or Penskes mount front and rear? I'm assuming they don't mount up using the stock rubber pieces.

Talking to myself, this is bad.
A follow-on question... I have -0.06deg toe in the front, and 0.08deg toe in the rear. What the heck is that in inches? (Stock C6 Z51 wheels+tires.)
Pelican Parts has a table for a 24-inch wide toe plate. 60 minutes to a degree. 1/16th inch ~= 8.9 minutes.
60*0.06 = 3.6 minutes ~= 1/48th inch
60*0.08 = 4.9 minutes ~= 1/32nd inch
If that's close to right perhaps the lacking toe-in in the rear is my mid-corner instability I've been trying to solve?
I can't wait for my Hardbar alignment toys...
Edit: Tape measure to tires show about 0.1in toe-out, and 0.3in toe-in.
