The rotors are lasting a pretty long time for me and are just starting to show signs of needing to be replaced (15+ track days)...

In addition, most pure racing cars run 2-piece rotors...the benefits on heat transfer and cooling are by far the largest advantages along with better handling.

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I spoke to Livermore Performance today about 2-piece rotors for the 996 Carrera 2. Upon learning that there were not very many companies making them, the gentleman I spoke to said they have the tooling available to custom fab some 2-piece rotor hats. All we need to given them are the dimensions for our cars. Upon saying this, he also said that the pricing would be spot on compared to other 2-piece manufactured prices.
If we had enough interest, I am thinking we could possible get a group buy going...
Side info: 2-piece rotors are a massive benefit. They reduce rotating mass and provide better cooling characteristics while on track. Better cooling also means better heat transfer, which equates to longer wheel bearing life.
Interest? What say you?
C.
2-piece rotors are a bit more expensive up front. Only recommended for track purposes. No need to change OE rotors if these are for street purposes only.
In the long term, you buy only the rotor rings. Which have a tendency to be a little less in cost.
C.
I could be interested...but if they're not going to be cheaper than what's already on the market then what's the draw over the ones that are out there and already proven?
Andy
Name some please. I have been hunting for a full front and rear replacement (OE sized) set of 2-piece rotors for weeks. All I can find are PFC's but they only come in the fronts. And, they require specially ground pads to work.
I have heard that AP had some, but I cannot find a table with sizing specifications.
C.
Yes. However...as I mentioned above.... PFC only has the fronts. And, they require specially ground pads in order to clear the rotor hats.
I am looking for a full (front & rear) set.
C.
I may be interested,depending on the cost of course, I will track the car 4/5 times a year so its worth it for me...I have TT tho so the price may be different.
Paul
Chad
I should receive mine this week (front), and they said no to the rears.
I am hoping they will make them soon.....or
If you get custom ones built our rears should be the same??? C4/C2 I'm in for (half)
Jerry
Do you know what rotor style and size these are going to be? I need some hats for a 355mm rotor with the Brembo 10x 233mm mounting pattern. If that's what they'll be I may get a pair of hats.
Chad...good point. I'm still on the edge on if I'm going to run a 2 piece rotor or not but I didn't realize that PFC didn't offer rears. I've seen AP's on a 996 but with AP calipers as well so I'm not sure if they offer a stock replacement parts or not.
Subscribed for more info...esp since I'm in need of at least front rotors before I hit the track again when it warms up.
Andy
check with HRP World, they can probably put together ones for you. IMO, if you are not having problems with the stock ones, I would spend the money somewhere else. I run Bremo GT3R 2 pc fronts and they work great, last 5x what stock was. I switched because I was only getting 5 days out of the stock cup front rotors
I am gonna ask a loaded question here... I really don't see my brakes as a weak link in the car at all on the track... Already have the Cup air scoops, SRF Fluid and Pagid pads.. Brakes are solid and fade free lap after hot lap.
I haven't even so much as fiddled with my brakes in over 6 months with lots of back to back track weekends. (I do check them of course)...
The rotors are lasting a pretty long time for me and are just starting to show signs of needing to be replaced (15+ track days)... I don't see why I would spend 3x the price of stock rotors for a 2 piece unit when the replacement discs for the 2 piece still cost more than a whole new set of stock rotors? Anyone else thinking this way?
Are these rotors even 1.5x better than the stock units... just looking for some helpful data here.
We are talking about DE usage not trying to win a trophy right?
Rotor wear is not the prominent point to 2-piece rotors. The point is much less weight and a reduction of heat transfer. Primarily to the wheel bearings.
C.
I'll disagree. The weight difference is minimal and the wheel bearings on the 996 MK II's, 997's and GT3 are not a real weak point. The real issue for those of us racing and really working the car is wear. As modifications go, this is one of the last ones I would recommend.
Chad, who told you that the pads don't clear the hats? OG Racing has told me that my current pads would fit the PF rotors without any fitment issues.
Dell, what's the difference between the PF97 and 01 pads? I track my 03 996.
Steve
as for wear, I've been replacing my front rotors after only a few DE's due to excessive cracking. I wait until the cracks get close to the edges or connect. The PF rotors are supposed to last much longer than the OEM, which is why the replacement disks are still more expensive than the OEM's.
Steve
My last car. PF proly got the combo down. Based on the photos of the most recent set for Porsche...this looks to be the case.
Glad they did...it was a PITA.
C.
With all due respect, I disagree...the percentages are around 12% lighter due to the materials used. Hats alone, made from quality aluminum alloys are perfect examples. Take all 4 corners into account...yes, it is a benefit. But, don't take my word for it.

There are other information sites out there that state the same thing. In addition, most pure racing cars run 2-piece rotors...the benefits on heat transfer and cooling are by far the largest advantages along with better handling.
C.
Guys, this really isn't difficult once you do the PROPER research. The 2-piece design allows for better brakes, is lighter, reduction of hear transfer, etc, etc, etc..
With respect to the PFC setup I have.........The real plus comes from LONGEVITY. Sure, my initial investment was $500 each up front and then $300 a set of rotor replacements after that BUT they outlasting 3 times as long as a CUP rotor that I was paying $300 for. Doesn't take a math wizard to see the savings.
