I am looking to upgrade my rotors/calipers and finding it pretty hard to find a decent set.

You can always go with Lucerne V8 brakes. Second most desirable set up and still a heck of an upgrade.

^I'll second that! I'm thinking the only difference is cast vs. aluminum...
Picked up a set of Lucerne V8 fronts at the Pull-A-Part last month. Calipers, brackets, and rotors (they looked brand new!) for $60! Would've taken the pads but they were cheap Duralast semi-metallics, and you guys know I love my ceramic pads, haha...

Right. I think the pad size is slightly smaller as well, but not by much. The litle bit of extra unsprung wight is not going to hurt.

I know I read on one of the brake threads the so called big brake set up took more footage to stop than the stock set up.

I spent 2-3 months looking for strut tower brace... It ended up being Google, found it for me. 1st match, for some reason, was eBay Canada. Seller was in Ohio, so when I searched US eBay, there he was, selling the same part.
I'm guessing the GXPs are either pretty rare, or people just wanna keep the car whole. Seems like you are kinda stuck, continuing to look, if you want that big. There are GXP racing brakes, but those are crazy expensive.
(& jofa is correct, the brakes require bigger rims, but I'm assuming you already knew...)

I already have larger wheels, they are the 18" Lucerne accessory wheels. Are the Lucerne calipers also 12.7"? I would prefer the larger rotors.

Yes, the Lucerne V8 front rotor is 12.7" (323mm) in diameter, same as the GXP. Lucerne V6 front rotor is 11.9" (303mm), same as the Aurora, but the caliper is a dual piston. Here's a pic from Kersh 's GXP front swap (18" aftermarket wheels);  FWIW, Kersh and other say the OEM 17" 2G wheels WILL fit over this upgrade. So Classic and 3.5 stockers are SOL on the "big" brakes, but not everyone  is "required" to go to a bigger wheel. Anyway, most big brake mods on 4 door sedans are done to compensate for loss after going to a bigger wheel, or aesthetics, not to improve on OE performance... |

I decided to go with some Baer Sport Rotors for the look. Could not find any good used deals on lucerne or gxp rotors. Normally the Lucerne rotors are $321.00 but he will sell them for the price of Bonneville which was $210. Baer only has 2 front pairs remaining and now just 1 rear pair. They have been discontinued so if anyone wants them you should contact BenN@baer.com directly. The Bonneville 12.715” diameter 1.27” rotor thickness 2.04” overall height The Lucerne is 12.714” diameter 1.187” rotor thickness 2.05 overall height  |
