I searched but I'm seeing some conflicting info. Some say the spindles are identical, some say the C6 has a shorter arm where the tire rod attaches.

I'm trying to achieve a quicker steering ratio on my C5Z, and thought this might be an effective route.

Thanks in advance.

Well I have not measured, but certainly the c5 is a radically better handling car, even if you swap all the spring rates and shocks back. Without measuring I'd stay with c5

They definitely ****ed up the rear bump steer in the c6, and I am not sure what else.

They are functionally identical. I put them on my C5Z and barely had to touch the toe adjustment after installation. I also went to delrin in new C6Z lower control arms at the same time.

They are as he said funcionally identical I have put them on 3 c5z's and the only change was like 1/8 inch toe. the angles on the turn plates are the same with c5 and c6 uprights when doing a caster sweep. I swap them due to bending the caliper mounts on our track cars, the c6 has a bunch more meat holding the caliper in place..
