C3/C4 rear strut rod length vs camber gain
Been wondering about the effects of changing the strut rod length on the rear suspension. I'm (slowly) completing the installation of a C4 suspension onto my spare C3 frame, and I'm getting a reasonable amount of experience customizing the suspension link lengths. Given that a front suspension uses significantly different lengths of suspension links (A-arms), is there anything to be gained (in the rear) by emulating this sort of ratio, or just lengthening the rods a bit?
Thoughts and opinions are welcomed.
Thanks,
Mike

C3/C4 Suspension
Mike,
I'm sure you know this, but the C2/C3 suspension had poor camber curves that could be helped by moving the inner pickup points down off the differential. Those strut rods are fairly long already, but could certainly be made longer.
Have you drawn/made your rear suspension paper model yet? You know, little paper arms, paper knuckles, all connectied with little brass rivits or something similar. You can move the susp. up and down and watch the camber gain/loss. Also do-able on paper with pencil, or even with CAD software.

Yes there is. GM basically stole Guldstrand's rear suspension design, but they managed to screw it up. If you take a look at Dick's suspension you'll see how much longer the links are
