They come up[ as the same part number.But if its larger you may have to change your calipers also...And check wheel fitment

I would compare caliper and disc part numbers on both. Then if that'* the same..it'* a different bracket. GM had done that on some cars in teh past.

Bigger rotors means different calipers and mounting hardware. I doubt the stock wheels would fit. Would probably have to get at least 18" wheels.
