While we're on the topic of good slotted rotors, can anyone point me in the direction of a good solid/slotted rotor for 993 turbo? A friend has 993 turbo brakes on his Cayman S and is destroying the drilled rotors, but is having trouble finding good replacements. Would prefer just the disc, but any option is ok at this point. Sponsors, feel free to PM me if you have ideas, so as to not distract the great Gt3 info in here, thanks!

... If you can only go 10 sessions on rotors, you need to stay off those things more!

Rep Power: 204 I dont know how long the PFC brakes on my cup will last though...Im thinking longer as there isnt nearly as much weight being carried around as my street 3 was.

After going through many sets of drilled rotors, I went with Brembo two piece floating slotted rotors. They are awesome. A plug for Dan at Vivid Racing for helping me. I think they are going to last much longer...

I think this has been mentioned many times, but DeMan rotors last forever. I have 50+ sessions on mine and they still have life left. Also, for the 6GT3 you can sub ATE Cayenne 350mm rotors and get long life for around $130 per corner.

The cracks are very common on the OE rotors especially after a few hard track days. Most of our GT3 customers replace their stock rotors with the GircoDisc slotted Rotors. They will provide a little more bit and will certainly stand up to the beating much better. Feel free to contact us with any further questions or you can feel free to contact RSS directly since there in your backyard.

Dont cut corners with brake rotors. Get the Brembo ones that will last you 3 times longer then stock. They have Patented McLaren floating hardware to give your rotor a true center line in braking. This also means you will never replace the brake hat where with other options, their spring/clip makes the rotor hat a consumable. The Brembo has a properly engineered vein design to best dissipate heat. The same manufacturing and testing that goes into their motorsports teams and big brake kits is what produces these. Do it right the first time!

Street miles don't really matter, but 10 "hard" track days can do in a set of OEM rotors. It depends on the track too. Some are harder on brakes than others.
Its really critical to let rotors cool down before stopping. Keep in mind that as pads wear, there is more heat transfer to the rotors. I change them when they get below 40% and save them as track spares.
I tried a couple of the non-OEM slotted rotors in previous seasons. Wasn't happy. But I have the GiroDisks on now. The build quality is excellent. Only have about 9 hard days, but they look good. A friend got 28 days on his GT3. I recommend them.

has anybody contacted Porsche regarding the cracks? For a street legal track oriented car, you would think it could with-stand track conditions when running on OEM equipment (DOT tires, factory pads, etc.)

Seriously Niel,
with today's economy and Porsche hell bent on remaining the most profitable car company, selling more brake rotors and parts when the customers wear them out driving on the track..... would you (if you were Porsche AG) give them race parts and technology for no extra charge?
weird expectations. The GT3 is a gift to those who like tracking. The components are durable and adequate for street driving if used as street car which sees occasional days at the track. Who else feels shortchanged by the fact that stock rotors are not adequate for pure track use?
