would love to swap mine out for some brembos. but i know the cost is about a couple of grand, plus you got to have rims that will clear them too.
If you are gonna do a swap you might want to look into Wilwood or Bear first to see the price differences.
I love my Brembo brakes! I had to get used to my 6 piston Brembos wanting to put me through the windshield but none the less, I replaced my Brembo pads after just a few thousand miles. One reason was the brake dust was a killer. The other reason was that I kept hearing about how those expensive 2 piece rotors wear out rather quickly with the OE Brembo pads. I've met a lot of people that have done it for the same reasons and many had recommended the PowerStop Z23's. I got the PowerStop Z26 Extreme Carbon Ceramic brake pads all around(total: $128) and I'm quite happy with them. Hardly anymore brake dust and they stop really good. Now I don't know how they compare for track racing but on the streets and at the drag strip they feel just as good to me. I feel the 15.4" rotors have a lot to do with it.
The SRT's came with the 6 piston Brembo's The RT Scat Packs come standard with 4 piston Brembos. Unless you get the optional Dynamics Package or the Wide Body Package. As ZEN357 mentioned, I think the Wilwood or Bear are worth looking into also.
