The stock 300C with the 5.7 Hemi DID NOT come with Brembo brakes, unless someone has done the changeover somewhere down the line. Anyway, since both vehicles are the same basic platform, it shouldn't be a huge problem, other than swapping all the needed parts. If you're not aware, the Brembo stuff is worth a lot of $$$ and, if you're getting a good deal, buy them, if for no other reason than to resell them. You will probably need to get most of the front suspension (hubs, caliper mounts, etc.) and put 20 in. wheels, as the rotors/calipers of the Brembos are much larger than the ones you currently have, and your 17 or 18 in. wheels probably won't accommodate them without hitting the calipers. I have both an 05 Magnum and an 06 300C SRT8 and I can tell you the Brembos are something to behold on a 4300 lb. vehicle. IMO, they're one of the better features of the SRT8, aside from the massive engine power and torque. I'd love to put them on Maggie, but for the cost. Maggie's brakes are not that bad, but the Brembos are just sooooo much better.
Also, while you're at it, if it is a true SRT8, at a minimum, swap the sway bars too. If you want it to handle like it's on rails, take the springs and shocks too. I have SRT sways only on Maggie, as I didn't want the harsher ride, but just the sways make a substantial difference in cornering without sacrificing ride quality. I have the full Jeep SRT8 suspension on my Hemi Jeep Grand Cherokee and it is a real hoot to drive for a big SUV, but is also very harsh, except on the highway.
