C6 Z51 rotors on base C5?

So I've got a car coming into my shop tommorrow that we're trying to fit c6 z51 rotors to. I've seen tons of threads involving this swap but most everyone is running aftermarket 18"+ wheels. Does anyone know for sure, as in first hand experience, that they'll fit behind the thinspoke y2k 17" wheels? There are a couple threads saying it'll fit behind the 17" c5 zo6 but no one with pictures and definitive proof they'll bolt behind a thinspoke. I've got both the c6z51 stuff and regular c5 stuff in stock and I can test fit tommorrow but I was hoping for an answer before I went blindly in. I just assumed that since a cts-v brembo would fit behind a wagon wheel on a 13" rotor that these smaller calipers would work. Guess I shouldn't assume, huh?

never assume, never would or should

they do fit, I tried it when I was down in FL working with EG, never street tested the car though, maybe an 1/8" clearance, deflection on wheel bearing???????????????

If one were to shave just a HAIR off the top face on the outside of the caliper I think it'd work. Although it wasn't my car and it would've totally defeated the purpose of putting those shiny red powder coated calipers on.

Now that I think about, GM had used slip on spacers on older trans ams/camaros and one of those 1/8" slip ones might even provide the clearance required, it's hard to say. Wish I had thought of that sooner...

I will say though, the red calipers and drilled/slotted AC Delco rotors look great on his car.

Also popped on a c6 Z06 shifter and aside from the stock boot not completely covering the stick that seems to have gone in with no problems either. I didn't drive the car, but hopefully the owner likes the mods.

Just hope the wife doesn't notice the bright reds.

Why would it make a difference?

I tried to bolt a 17in C5 Z06 front wheel onto the front of a C6 with Z51 and the wheel rubbed the caliper. Just barely but enough where I wouldn't do it.
