Track doods: 2-piece rotors. Found some interesting info

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.

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?

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.

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.

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.

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.

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.

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.
