Those have 398mm front rotors with around 3.5 to 4mm bigger radially front calipers over the regular Gen 6 ZL1-sized caliper? The copper free brakes (BCD option) for 2022 Model Year is driving that.
The larger front caliper I referenced above is also on the new CT5-V Blackwing with the same caliper body (not pistons) between the steel brake (J6H - 398mm rotor) and carbon rotor (J57 - 400mm rotor) versions.
On my 18x11 +7 SM-10, I have only 3.5mm clearance to the cross-over tube on the Gen 6 ZL1 caliper. I could not properly fit that new front caliper as-is with the 18" SM-10. My Texas dealer friend has a SS 1LE inbound with those brakes, and if I get the chance, I'll try myself to verify just to check my data from measuring my caliper vs. a CT5-V Blackwing I did. Didn't have the wheels yet to check on the Cadillac.
Love the new forged wheels of your coming, but, want clarity on this just in case I end up with a 2022 at some point because the larger brakes are only a $500 option.
