G8 GXP used 12mm bolts to secure calipers to front suspension uprights.

PPV uses 14mm bolts in the same positions.

Are the calipers (front only?) from a 2009 G8 GXP, or was the car a G8 GT converted to Brembo? I ask this because of your subject line--G8 was fitted with Brembo's in 2009, to GXP only--not available in 2008 G8 GT.

IF the calipers are G8 GXP originals, you have two options:

1. drill & tap the caliper mounting "ear" holes to M14x2.0 thread and use the PPV bolts to secure the calipers
2. obtain bushings to reduce the 14mm holes in the suspension to 12mm ID, and use 12mm bolts from G8 GXP to secure the calipers

Option 1. is the better choice, IMO. If you're not comfortable doing that, find a competent machinist to do the job, or get the correct calipers (with M14 holes) from a 2010-2015 Camaro or 2014-2017 Chevy SS Sedan.

The plot thickens....

The front Brembo calipers COULD be either 12mm or 14mm thread, as already mentioned.

All rear Brembo calipers use 12mm fasteners.

The Brembo brakes use specific rotors and brake pads--just wanted to clarify this so it's understood that there's more to this than just swapping calipers.

Plenty of other threads that already cover all the details.
