993tt rotors...... any reasonable upgrades from stock?
Found out I needed to get the 993tt rotors for my EVO upright conversion. So, since I need to get some anyway, thought I'd ask you guys if there is anything out there (aluminum hat/rotor) at a decent price worthy of upgrade.
Anybody with a hot tip???

Hello Dr. the stock 993TT stuff is excellent. For a street car I would really not spend a penny going lightweight or especially any larger. 
If you "must" change, then the easiest is to go the Brembo GT way and having no fitment headaches.

Yes, there are some racing rotor hat assemblies, but they are overkill for a predominately street machine.
These are an AP 332x32mm rotor/hat that fits nicely under the TT calipers using some custom caliper adapters. For track use, these are FAR better than the OEM ones for durability when using race pads and the additional thermal dissipation capacity is very nice to have.
This is much less expensive than the Brembo GT 355mm kit,....

IMO - there are no decent rotor upgrades for a street car. OEM are just fine. In fact, I found the OEM rotors just fine for track days with 450HP. The cost of all upgrade rotors simply does not make financial sense.
As others have pointed out, the only true upgrade for the brakes is a big brake kit; Brembo's are excellent.

Interesting thread and topical issue for me.
My 590hp 993tt original brakes has come to end of them stopping power. For now brakes are prevent my lap time advance.
I have race brake fluid (not silicone), stainless brake hose, techart brake cooling channeling and semi slick tyres. I assure you that all of braking power of originals are used and not enough anymore!
Brembo set up can't be bad choose, but what set up? Drilled or slotted or ceramic disks? I prefer slottep after many many changed cracked drilled disks but can someone explain me the difference of those two (drilled and slotted). I'm just considering cooling capasity of slotted ones? Wet wheater character I don't care.
6- or 4-piston caliber? It's confusing you'd think 6 is better than 4, but top of Brembo range calibers are with 4-piston? And 6-piston is heavier. Don't know which ones?
Disk diameter is also confusing you'd think bigger is better. In other hand weight increase and spinning forces increase?
Some brake guru please little help here

Tell us what you are experiencing that makes you think the brakes aren't enough.
My 930 has 514HP and with the 993TT brakes I have, I assure you there is plenty o' brake there after 120 track days over 11 years - not a newbie here ;-).
Fluid boiling? Soft pedal? Pad fade?
What fluids and pads are you using?

Fluid (Motul RBF600) isn't boiling, pedal stays hard and no considerable pad fading (can't tell for sure). I have tryed originals, Ferodo 2500, EBC red stuff and yellow stuff. Haven't tryed more agressive pads because I HATE that scream when pads are cold and driving on public roads.
For excample braking from 200kph to 70kph I cant' reach ABS cutting any wheel even I push all I've got from my leg. Which is good, I don't want ABS take a part BUT I can feel with more grip between disk and pad will have postive effect for my braking distance because my tyres can carry more grip when braking.
930 is much lighter than 993 and which tyres are you using?
