Just a couple questions and fruit for thought here
1) Think they'll just bolt up? They're the same bolt pattern so I think they might, but not for everyone obviously (I'm running 18 in wheels just like the Super so I have the clearance) I'm in need of brakes anyway and I'd like to stop this boat a little more efficiently with less brake fade.
2) I'm not sure if they're the same as the GXP ones or not.
There's documentation on those but no one talks about our fellow Buick cousin.
3) Would you need to get new calipers or are they the same/close enough?
