Report on PCCB to iron rotors for my GT2
As posted before my PCCB rotors were toast after about 10 track days. The wear circles looked like someone took a chisel and gouged out material and parts of the rest of the surface were starting to flake off. The replacement cost was $3500 per rotor so I decided to switch to iron. I don't know if the PCCB problem was my early driving style with TC/SC kicking in, a design problem or a combination of several factors and not knowing if it would happen again dictated a lower cost option.
On Friday I took the GT2 down to Sharkwerks for Brembo two piece iron rotors on front and rear. Fronts are 380mm Type III 72-vein rotors at a cost of $2,595 for both. Rears are 350mm Type III at a cost of 1,995 for both. Best of all, replacement cost is about half that as the hats can be used again. Pictures of both are on the Sharkwerks web site. Note the fronts require a special motorsports pad with a smaller backing plate so it clears the hats(They are Pagid yellows). Alex has posted pictures on 6speed.
Took the car to Laguna yesterday and was pleased with the conversion. I didn't notice any drop off in braking performance and actually felt the Iron rotors gave better brake feel and control. This may just be new toy syndrome--I did it so it must be better. Also, the iron rotors were easier on pads--not as much wear and not as much discoloring due to heat.

I've got some pix etc....
Here we are swapping the PCCB rotors out for some 380MM assemblies that use full race Type III 72 vane wide annulus two piece rotors.
Stock fronts coming off...
Here are the fronts installed...
Stock rears (these are something all 997TT & GT2 PCCB owners need to keep an eye on) about to come off:
Comparison...
On go the brembo rotors in the back...
Off home... Oh and you do get brake dust now

Rocket: I never thought about using the PCCB hats. Anyway the fronts still look fine so I put all the PCCB stuff in a box to save in case I need to restore the car to stock.
Crazy Canuck: No warranty coverage because of track use.
iLLM3: I wish I had your foresight and had taken the ceramics off right away. Live and learn.

My car has brake dust after track use that looks like sand, I am scared the rotors on the rear will not last long.
I think Porsche over did the computer safety devices, trying to rid the widow maker title!
Did you know you can not turn off your PASM, which I do not like!
Can you use the P50 Motorsports pads on the front and rears with these rotors?

If you leave TC ON and are hard on the gas you will overuse the rears as the brakes are what prevents the rear tires from spinning. 99% of the problems I've seen people have with GT3 and GT2 rear brakes are because of the use of TC. Just take it off and be sensitive with the throttle (Especially in a GT2).
Also the P50 pads are the "track" pads for PCCB but they are a LOT harder on the rotors. Contrary to steels', the PCCB OEM pads work fine at the track. They do wear relatively fast (4 - 2 hour track days for the fronts?) but are a lot easier on the rotors.
I've had no problems with my GT2 brakes and I've always driven it with SC and TC off, even as a daily driver on the street and through the winter.

Z06: Don't know about the P50 pads use with iron rotors. I suspect the fronts will not work because the rotor design requires a pad with a smaller backing plate so it clears the places where the rotor mounts to the hat. The rear rotors will take any pads but I don't know how the compound would work. Interesting question since I have a set of partially used and a set of new P50's for the rear. Maybe Alex can chime in with an answer.
cgomez: I did start out with TC/SC on and maybe that was the cause or rotor problem. But, at the cost I wasn't going to try again with new ceramic rears. After one track day I really like the iron rotors.

FALSE. PSM (SC in the GT2) and TC can be TURNED OFF and it will not come back on, even if you go to a drifting contest in your GT2.
If you leave TC ON and are hard on the gas you will overuse the rears as the brakes are what prevents the rear tires from spinning. 99% of the problems I've seen people have with GT3 and GT2 rear brakes are because of the use of TC. Just take it off and be sensitive with the throttle (Especially in a GT2).

On the GT2 the computers limits are set for granny driving!
I ment PASM, suspenison..shocks, I would like to replace the dampers but the computer will shut down, thinking there is an error in the system. There is no method of doing this.

On my previous Z06 the SC was very mild, it would allow slight drift, my friends new Evo it's computer allows it to rotate ever so slightly.

I see. PASM doesnt have anything to do with the brakes. I think it has been done by some Euro Tuners. I saw a several GT3 and GT2 and the NRing running non-stock suspensions/shocks

Could even be a simple resistor type trick used for airbags.

You mean the computer limits with PSM ON? The solution is to take it OFF and You driver the car, not the computers.

The stock GT2 computer is to intrusive, drive at 6 to 7 tenths or more and you destroy your rear brakes, what a joke that is...it's ticking time bomb!
On a Z06 or an Evo the limit is more like 8 to 9 tenths and they still don't self destruct.
Why is it wrong to expect a $200K car to have a system that will allow you to track it at 8 to 9 tenths like the other cars without the destruction of it's brakes?
Maybe your a great driver and are willing to take a chance or maybe you don't drive it at the limit, I am wimp with no driver aids the most I will push is 7 tenths...not willing to take a chance at a lapping day with my $200k car, at least not at a high speed track like Mosport, if it was at a safer track no problem.
I do not like how the stock PASM damper pitches, rolls and bounces... I have checked with all the Euro tuners nobody has a fix as of now for the PASM on a 7GT2.
997gt3 North,
Your correct on how they are going about fixing it, TechArt has dumy circuits on there Bilstein damper that does not function as PASM.
Manthey said that it's not a problem, but if you buy a KW system from them they will not give a money back gauranty if it does not work...because our mechanics don't know what they are doing it's not Manthey's fault?
BS!
