My original drilled rotors lasted more than 10 weekends on the track. I don't run 10/10ths but I don't think people buy TT's to run as 10/10th track cars.

 

I just changed my pads, the rotors were still good, I have approx 6 track weekends on them. Next up is a flush and bleed with some fresh GS 610 fluid and I should be good to go.

 

About 20 track days on my stock rotors in the red group, grooved a bit but still ok. When they're done I'll probably just put some stockers back on.

Ive done about 20 track days in my car, the problem is the cracks. Just about every hole has cracks coming from it. None are going to the edge yet and I still have rotor left, but Thom at Porsche of Huntington said if he was teching my car he wouldn't clear me with the rotors I have on now.

I really dont need an upgrade in braking performance so I think I'll just compare the price of the AP and the RSS and go from there, if there isn't much difference I'll give the RSS a try, otherwise AP.

 

Do you know the names of any of the ALMS teams that are using those discs?

 

That price would be for a set of FRONT & REAR.
We are only a week or so away from the rears being available.
Front alone retails for $1895.

The cost is pretty much in line with the AP units I was originally talking about, only a tad bit more because of the McLaren style hardware Brembo uses that allows them to be full floating.
(I think there's more than one AP version out there)

For any of the other options out there, I would be curious where they are getting their discs from. The quality of the disc is going to dictate the longevity, and the longevity is what is going to make them a value or not.

Weight savings alone does not justify the cost for any of these brands. The weight savings, plus the benefit of being full floating, combined with the benefit of lasting twice as long as the OEM discs, definitely does.

 

Just for your interest--- DeMan Motorsports--High Performance One Piece GT3 Rotors
2 times the life of factory rotors, fits 997 GT3 Street 06-08, GT3 Cup 02-05, 996 GT3 Street 04-05, $695 per pair, http://www.demanmotorsport.com

No affiliation blah, blah, blah. Never tried them, just thought you might like to see these.

 

Deman's GT3 fotor does not work on the Turbo. The offset is different.

 

Sorry, I upgraded to GT3 brakes and wasn't thinking about the turbo aspect.

 

You pulled the front diff and changed out to GT3 hub/wheel bearing?

 

No, just changed the calipers and rotors. Since then I have to think of GT3 parts when I think about brakes, therefore the mix-up.

 

20 track days? Hell, just buy OEMs and be done with it.

What pads are you using? Try the Pagid Yellows..........here is a good place for those:

Switched to Pagid Blacks after about the first 7-10 track days. I'm definitely going to go with a slotted rotor, just need to figure out which one.

Also, my car gave me the Brake Pad Sensor warning today, but I checked my pads and I have a ton of pad left, can the sensor go off for rotor wear?

 

Mine went off when I had more than 30% or so left.
You might have pad taper - one section of the pad more worn than the other.
I'd take them off and take a look.

 

That happened once on my old c4s, the sensors had melted when the fluid boiled at limerock.
Also make sure your wires aren't loose or contacting metal.
