Unfortunately the B9’s have a completely different rotor setup from the B8’s and the R8 so there aren’t any plans at this time to make a fitment. The rear setup wouldn’t be as advantageous due to the small disc size plus I can’t see many B9 owners spending $12,650 on carbon rotors.
Now if there’s enough interest, we can produce them but it’d take at least six owners willing to commit with a deposit.
The B9 front rotors (iron) are 375x36mm and those dimensions aren’t shared by any other brake disc for current Audi vehicles. On the B8/B8.5 RS5, the front rotors and calipers are the same as the R8, Huracan and Gallardo so there was a good business model to bring that fitment to market.
These rotors will be used in the United States International GT Car Racing Championships btw…International GT is a North American racing series that includes three different championships for late model Porsche and Ferrari competitors. Home primarily to sports drivers, with the occasional professional driver/coach joining the action in endurance races, International GT annually presents The Stuttgart Cup, Mission Foods GT3 Cup Trophy and The Maranello Cup championships. The Stuttgart Cup includes Cayman 3.4 and 3.8 liter cars. The Mission Foods GT3 Cup Trophy features 996, 997 and other GT3 Cup cars from the last decade. The Maranello Cup includes Ferrari 360, 430 and 458 challenge spec cars. All classes compete for season-long sprint championships.
So pretty serious stuff which’ll really illustrate the benefits of the ST rotors over iron and traditionally manufactured CCB rotors.
