I am running the PFC 7819.08s and they fit without any mods but like I said, it's tight. Oh, yeah, and on the 380 steels they are painfully loud. Hopefully once fully bedded in they'll quiet down a bit.... The interesting part is that when I ran the 350 steels with the PFC 08s, they were fairly quiet. Oh well.
Heard the sam(pun intended) Thanks again for the input.
The only problem you are going to have if you convert to steel on the 380mm rotors is the fact that nobody makes a steel rotor that has the same width annulus friction surface as the factory PCCB which is around 72mm if I remember correctly.
Hi Powdehound I am researching for the replacement rotors. Can you be more specific about the annulus of factory PCCB rotors. And if only the narrower annulus rotors (65-66mm) are available as you said, would it cause any concern at all.

Powder hounds point is replacement 380 disc up front have a smaller swept depth aka annulus width which limits you to a smaller selection of pads. Most of the compatible pads are race compounds however you could probably find a steet pad available that would have to be modified not to hit the hub.

These are "narrow annulus" 380 rotors. The narrow annulus rotors use a narrower pad to clear the hat. That is the only difference. The narrow rotors will be a little lighter for obvious reasons but will have less thermal dissipation than the wider rotors.

These are the "wide annulus" 380 rotors. These are the same as PCCB.
You can see that the pad is wider compared to the picture above.

Not right now though. Giro hasn't had the 380s available for the last 6 months and as of right not there is no availability. Only 350 Giros for the TT right now. The new 380 rotor design should be released fairly soon but not as of yet.
