Yes, I know Tarox make some with the rotor you like. They even make a complete
312 x 25 6-pot BBK.
These Performance Friction aren't drilled though, just ''dimpled''. PF does it on many
'Direct Drive' kits.
Believe me, they are even better than Tarox. No need to talk about prices. If they
would still make them, I'd bet they were close to 1000,-- €.
BTW, I'd bet these discs are "Direct-Drive" (truely floating), but no safe information
currently available.
