Anyone know if the Bonneville GXP front calipers and rotors work for the 2nd Gen? Same chassis, same knuckle? same bolt pattern, etc? i already have the Grand Prix GXP brakes on my '03. i'm looking to upgrade my '01 and don't really want to go back to the GXP setup because of the brake lines.
*note Brake lines started rubbing on my wheels and had to bend them back. running a 20 X 8.5 inch wheel.
The Bonneville runs the same chassis as the Aurora. In the Grand Prix does not. The calipers are similar but I believe the Bonneville calipers are slightly bigger. Also, the Grand Prix calipers are aluminum

Aluminum calipers sound nice. Are the pistons also aluminum? If I wanted to go up wheel size I would do that just because rust kills everything up here. And aluminum doesnt rust, just corrodes slightly.
I'm not sure about the Pistons. I can tell you that they are significantly lighter than the stock brakes and there are two Pistons compared to one. The only thing that is a pain in the ass are the brake lines. You have to run the ones from the Grand Prix and you have to sort of finagle them so they fit right. I'm talking about how they're angled. The bolt up just fine.
