my car is track only and i run stock rotors with pagid blacks. no problem stopping, just can;t be too late on the pedal. I was thinking of going up in diameter for the endurace reasons. What are the cup cars running ? 355 all around right ?

Stop tech is poo poo IMHO. I used to have a kit made by Movit on my audi S4. Big reds all around with Porsche rotors. That was nice. Stop tech made a kit for the Audi S4 and my friend had to send back the calipers 2 times, they kept seizing up. Hence my poo poo comment

That said I echo the sentiments of others that the 993TT brakes are not the weakest link for someone who appears to be a novice driver looking to participate in a HPDE. Seat time is the best thing to focus on along with sound instruction. When I started out my biggest (or is that first?) mistake was rushing to modify my car before learning the cars driving dynamics in stock form. Just must my 2 cents

They have been most reliable and StopTech's tech support has been superlative. I have no problems with Brembos, Wilwoods, or any other after-market BBK that has been mentioned in this thread. Just wanted to say that I have had excellent success with StopTech and would recommend them without hesitation.

Roger that. My stoptech experience was 7 years ago. I'm sure they have perfected the systems now. Either way I race with stock big reds and pagids and have had no problems. i've also driven this car on the track for 4 years and prior to this one a 930 so i don't use the brakes as much as i did when i first starting tracking.

StopTech comments: I ran ST on my 993TT Andial with no issues. The brakes were great for street and never faded at the track.
AndyT's comments about his experiences 7 years ago: In the very early kits, there were a very few instances of corrosion-related issues that could have caused binding. All of these issues were addressed and dealt with more than 5 years ago.

First, the stock set up is good with up to 450hp. SRF fluid and good pads help a lot for sprirted driving and light track work. If your doing wheel to wheel and a lot of track, get some active brake cooling and they'll survive.
For big HP or for you left footed brakers the Brembo GT as mentioned are a great upgrade. I've driven a dozen different turbo's with all kinds of brake configuations on track. I liked the Stoptech's the best and I've got Brembos.

More Stoptech feedback: I installed them on my E46 M3 (355mm rotors, ST40 calipers, all four corners) and found the quality and performance of the kit to be superlative. I installed the equivalent Brembo kit on a friend's E46 M3 and although there's little practical difference, I prefer the Stoptech.
And if nothing else, I believe the owner of Stoptech drives a 993TT...

I also heard good things about Stoptech, however if budget is not an issue, I would not trade a Brembo or AP racing for them maybe, but that could be due to the bias some of us have about brands that we know, not due to technical merits.
I tend to disagree with the direct HP/brake relationship.
I would focus more on the type of usage (DE vs. Sprint vs Enduro). I cannot foresee where someone might need bigger brakes than stock on the street... under any circumstance.
I only run Sprints and Hot lap trials, often in ambient 110-120F+ and never had any fading, my car reaches >160mph in the straights going into 1st gear hairpin.
If I had any issue with braking I would have upgraded discs and calipers(maybe only thing I still have stock
). As JJayB mentioned, SRF, new pads, GREAT bleeding, everytime clean up/drill the cooling passages in the rotors and duct some air through them.
Bigger 6 piston brakes might give me a few tenths around a lap, I make up the loss on exit
I might be lucky, I don't know.
