From what I can tell no. Both the rotor and the caliper have different part numbers

Does the GP GXP come with 18" wheels? I would think the brakes are different. The GXP has an FE5 front suspension that was specific only to it.

The fronts are the same. Rears are not. Both have 12.7" brakes up front.

The front calipers on the Grand Prix might be the same size but have GXP painted on the calipers whereas the Bonneville does not have GXP on the calipers which would give it a different part no. ,but they look the same size

the rear calpier is different, in the way it mounts on to the Lower controll arm. It also has a different bracket because of the LCA

the Fronts will not bolt up there will have to be fabrication
