I was considering this upgrade as well and the calipers mount to the same points as the pre 08 models. Rotors need to be changed and caliper bolts need to be changed as well (Brembo's are shorter). Banjo bolt on the master cylinder needs to be changed if using the stock M/C which some that have done the conversion say work with the Brembos, BUT the Brembo system uses DOT4 whereas '04 uses DOT5. Complete, and I mean complete system flush is needed. Best bet is to get the calipers, lines and M/C used from eBay and you should be able to get everything for $400 or less if you're savvy. I've held off since I'm not really convinced it's worth the $$$ to do the conversion. Mine stops fine the way it is, even running a single calier setup. JMO
