* 8.8-inch 10-bolt: This was the standard rear axle for most models.
* 12-bolt: Some higher-performance models, particularly the ZL1, used a more robust 12-bolt rear end. This is significantly stronger and designed for higher horsepower and torque applications.
To know for certain which rear end is in a *specific* 2014 Camaro, you'd need to check the vehicle's specifications (often found on a sticker in the doorjamb or the owner's manual) or look at the differential itself.
