I'm looking for a pair of 300mm rotors w/ 64mm bore, 6-bolt 80mm pcd and 18-30mm (28mm?) offset. There was a Brembo rotor but it's discontinued I understand, any other solutions?

Carlo Leoncini would probably be your man - he's a member on here & from all accounts makes some pretty spectacular stuff for our bikes.

I have checked his site and only see brake discs with 80 mm bore, though because of your suggestion I just sent him an email.....
A question regarding these discs, was this an OEM/Brembo part that came on a production Ducati, or was it and aftermarket/race part?

Thanks, I checked out the site but that disc is the more available 10 mm off-set. The disc I am looking for needs to be in the 18-30 mm range for off-set, I understand the Brembo was 26.5 mm.

There is a set in Germany ebay: http://www.ebay.com/itm/150676537985

The brake disc from Carlo are aftermarket but best quality.
Best choice if you cannot get original Brembos.

Horst, I've sent a message via Ebay asking the seller to confirm the 64 mm bore and the 26.5 mm offset. Thanks for looking this up!

John,
Those ebay rotors look like a n.o.s. set of iron 300 Brembo's, same as on my TT, which are really good ones. Can't translate the info and don't know what those marks are on the rotor surface. If they are the same, the pilot i.d. should be about 80mm, and offset about 24mm (across the wheel sides of carrier), and approx. 101mm bolt circle. My bikes and tools are over at Robbie's from coming back from Barber, and can't get to them until Sunday for a more accurate measurement. Haven't seen a new set of those available for a while. Hope this helps.
Bill

Bill thanks, that's what I suspect. Sigh... naturally I have a brand new set of Dymags with a 64 mm pilot OD and an 80 mm bolt circle. It looks like I'll be using a 90-91 Passo/90-95 FZR600 disc w/10 mm off-set and spacers behind them.

That is a hard size to find; the old 300mm OD with the newer Yamaha/Ducati 64mm ID and 80mm bolt pattern. Yamaha TZ rotors are like that, but only 10mm deep (essentially, flat). Yoyodyne (in US) can get new Brembo versions, and you could then make some spacers. Not cheap, but would work.

I have a used set with your specs, but with shop-made (unknown source) machined aluminum centers, floating anodized buttons, and CI discs. The centers look like pie plates, but the buttons and discs are actually sound. Would sell them to you fairly cheap. Let me know if any interest. MikeV
