Any C5 track cars here running C6 suspension parts?

I've seen the C6Z06 rear cradle used with the 6060 conversion in the C5

Has anyone measured the L/UCA's to find the track difference?

Spindles?? The C6 base spindle has changed from the C5, does the ZR1 also differ from base C6?

Thanks

I'm running the ZR1 spindles on my C5. They bolted right on. The most noticeable difference is the mounting bosses for the brake caliper, much stiffer and bigger.

Steve,

I put C6 front knuckles on my C5 when I installed my C6 ZR1 carbon-ceramic brakes. All C6s made after the introduction of the ZR1 use the same front knuckles. Part number is 88965637 and 88965638.





The following picture shows the C5 knuckle on the left and the C6 knuckle on the right. Please note that the C6 knuckle is significantly beefier in the caliper attaching area. Also, the C6 knuckles steering arm is shorter than the arm on the C5 knuckle.

C6 steering arm is shorter?! Damn, I might need to swap some in.

Pumba, was Center of axle measured to center of tie rod hole to verify this?

Thanks for the pics and info

A Plan-view of both the C5 and C6 part showed the shorter steering arm.

I intend to put C6 spindles on my car some day, but has anyone ever actually had an issue with the C5 spindles or are we all just following internet hype?

I have a friend inside GM.

Bringing this back up.
I bought some non-ZR1 spindles removed from a 2010 C6Z and the steering arm is actually a 1/4" longer than the C5 spindles. Anyone else notice this?
