I can't seem to find a definite answer to this. I know the Z06 rims were cast and not forged, can anyone clarify if the ZR1 rims are forged or cast?

I think they are spin forged.

Zjoe6

Flow Form forged. Fancy way to say spin, rotary forged etc.

Are these chinese like in the other C7s?

My Grand Sport were made in Mexico, Speedline.

I'm pretty sure all the Z06 wheels were cast and made in Mexico. If these are flow forged they should still be stronger and a hair lighter than the Z06 wheels.

Ask JerryU about that. He found some place that quoted Tadge being specific about it but I didn't have the source of that quote.

May not be the most reliable source but the June 2018 Car and Driver magazine list the ZR1 wheels as cast aluminum.
Don't have a link but did save the magazine.

See below link to thread that Tadge answers on this.

".....In fact, Z51s have forged wheels, while GS, Z06, and ZR1 have cast/flow-formed wheels, all of which had the wheel construction chosen for optimal wheel design, styling, and robustness."

Cast and flow formed have such a different process how can Tadge say "cast/flow formed" which one is it? Flow formed would be better for strength and that's what I'm hoping to see (Z06's had issues with cracked rims).

Is "Cast/Flow formed" the same as, "Cast-Spun" Where they spin the mold while pouring in the Al?

Thomasmoto

Pretty sure this is correct.
