First off, decide WHY you want the SRT Brembos. If it's just so you can say you have them, you can find more constructive ways to spend your money. If you're trying to build up a car for auto cross or similar and NEED bigger brakes, the only real way to to find a wrecked one and strip the entire brake system off it. Unlike older cars, you have a sophisticated ABS system and getting it to work properly will be your biggest problem. Keep in mind, larger brakes may require larger wheels. This will reduce sidewall height and give you a lower side profile. Lot's of people like that look but the ride quality suffers. If you just go with taller tires to get a better ride, it won't hold in the corners as well and your speedometer will be off. Since you have an R/T, the cops eyeballs will click when you go by and you really want your speedometer working accurately.
Without knowing what you have in mind, that's about as good as I can tell you. Personally, I'd see how to upgrade the brakes on the car I had now. Would the SRT calipers fit on the R/T mounts? will the mounts swap? Does the SRT have larger interior diameter wheels? At least ALL cars now have disc brake wheels. A salvage yard I used to run got an old Blazer in with a locked up front end. I wanted to sell the rims off it and had to use a 20 pound sledge hammer to get them off. They had used drum brake wheels and they jammed against the calipers due to a low inner curve instead of the wide curve on disc brake wheels.
