there is no difference in the braking specs of a regular CTS and a sport Pac. The suspension will not cause any problems either. You're fine don't worry about it, Cadillac doesn't put much into their sport packs, like other brands such as Mercedes (I couldnt put 16's in place of my factory 17's because of the monster brakes on the sport pack.

Thanks to everyone for the info! I wasn't sure about the rotor diameter - I guess the "upgraded brakes" just use a special pad spec that creates more dust on those nice 17" wheels...

I'm not even sure if the brake pads were upgraded as part of the sport pack... Sport pack I - 17" wheels, sport suspension, sport steering, stability control. Sport Pack II - All of sport pack one equipment PLUS auto load leveling rear suspension.

atleast thats how they were equiped in Canada in 05'
