gxp brakes
The Factory drilled GXP rotors are junk. Do searches. The calipers front and rear are the same as a C5 Z06. I'm surprised the rears on the GXP are bigger. I have a lot of experience with brakes, tried several combos. This is what I plan to do on my GXP. The drilled rotors are for show ONLY. They will stress crack eventually if driven aggressively. Get a high quality slotted or solid rotor . Delco advanced tech, rotors I put on my Z06 with just Hawk HPS street pads, SS brake lines and Prestone Dot 3 syn brake fluid. After that my braking sucked my eyes out. The G's it would pull were incredible for such small brakes and 2 piston front rotors. It was the sum of all the parts that made my brakes feel like a big brake kit. I did lots of searching and got lucky on a couple things. The brake fluid, pads, and ss lines helped a lot IMO. Budget but was night and day from factory set up. BTW when I drove my buddies 2007 C6 Z06, his big drilled 6 piston brakes didn't come close to my little improved ones on my C5. No good initial bite or overall short stops. Felt kinda mushy. Bigger isnt always better. Beat him in autocross as well. Both T56 manuals.

So if they are cast like that instead of manufactured solid and cross drilled by a machine after they are more durable? Hmmm I'm glad you love yours but I would never turn rotors.My old buddy is a Delco/GM parts rep so I have learned a lot of inside secrets. He says never turn rotors. They will wear out your new pads faster in most circumstances. How bad were yours warped, bumpy or lumpy? lol.. maybe the GXP is different. So do your brakes suck your eye ***** out where you get on the brake pedal from high speed? If they do I will buy new GXP rotors with Hawk pads, ss lines, Prestone Dot 3 syn brake fluid My brakes are all original and I can tell maybe pads replaced. Original rotors brake lines , doubt it ever got re bled. It kinda grinds at times. Of course they aren't gonna stop like my Z did. Different strokes for everyone. Just never been a fan of cross drilled. I will do the brakes that I want later on this summer. (84K miles) Needs a refresh.

I had zero wobble however the surface was starting to get glazed to much so I have them turned every once in a while. The pads have a lifetime warranty so I just take them back an get new ones after they wear on th rotor a little.
GXP brakes are damn good best of the w-body crowd. Biggest rotors matched with PBR calipers and higher ratio brake pedal to stop faster.
If you want you can also look at getting the 14" /CTS-V 4 piston fronts for cheap as well.
If you want the extreme you can go 14" 6piston AMD 4 piston rear but that will set you back a grand

I have really good bite. An stays that way. I need to ditch the rubber lines though. I've been looking at c5 z06 rotors to have redrilled though as they are lighter than gxps and plan on getting some Cadillac ATS brembos instead.
WHY???
Derek
lol never said there wasn't room for improvment.brembos and z rotors equal less rotating mass and unsprung weight with more clamping force.
