Brembo

 

I need some slotted rotors, do you have any specs? Where did you get them? I would do anything to get rid of the drilled things.

 

I have same set up gt3/gt2 6 pot calipers and 997 tt front discs works great. I think the those disc are 355mm. now when i replace brake disc..oem 997tt.
I belive the curved slotted discs are alcons, I think.

 

Mine are Brembo which are 355mm, the stock 997TT are 350mm, The Alcons are also pretty good, size was 360mm (sure they went to 362mm with revised version) but you have to run an adaptor with the Alcons and you can't get them under stock 996TT Wheel (unless you start using spacers) Downside with my Brembo's is they rattle until heated up, just because of the design and it's a floating rotor.

 

BTW, IMHO, these rotors are really best for track, see you need to get them up to operating temperature along with the pads before you start seeing good results, the Steels (997TT) will operate just as good but they wear/crack very quick indeed, I still have a half used set of pads and 997TT Steels and have swapped them back once already for street use, just not had time to swap them back again since track season has finished.
