wogamax, I heard about PFC dust imbedding it's self into paint and staining aluminum wheels too if it gets wet. I never ran into that on the PFC97's I tried out back in 2008. I washed my car when I got home from DE's anyway.

What I did believe I noticed was that PFC97's at least transfered more heat to the caliper than Pagid Yellow's. However Imust say I was way over braking back then and have lightened up braking a lot since then. So I wonder if I could Run PFC97 or 01's now without the heat transfer?

TRAKCAR

PFC 01 = more heat and more rotor wear then 08 that's why I am trying 08 first.

I have a pair on my bench. I didn't want to go too far OT, but yes, the PremiumOnes can be had for $130ea, shipped, and are a great solution for late 996's and 997.1 steel GT3s. I was going to use them until I priced the knuckles for the GT3 red 6-pot calipers, at $2,500 a pair. That turned my OE/350 conversion into a train wreck, soon to be yard sale (Calipers back to Suncoast/restocking fee, won't be using rear reds, etc)

The slotted ATEs are heavy, at 28lbs, but are being used with solid feedback among the "steel 350 crowd". Its rediculous, to me, that Porsche didn't simply offset their yellow calipers further out. Instead, the castings of BOTH the caliper and mounting knuckle were changed merely for the PCCB option, and probably all other OE 380mm diameter fitments. You can't "shim" a fix for a bolt hole spacing change and, unless you buy the knuckles, you can forget about using these rotors.

This has come up on the board in the past, but it isn't an obvious thing to look for. It's another reason for a GT3 brake FAQ, IMO. I think economics heavily favor the original 350mm design, if that's where you started. $2000+ per pair of PFC/Giro/AP/Stoptech is a joke next to the $200 ATEs. Friction rings for $1000 a pair, c'mon?

If I were running lots of days at an uncambered, technical track, in a hot climate (aka Sebring), I would have paid up for the older knuckles and done the swap, but I probably won't go through more than 2 pairs of OE 380 2010 GT3 steel rotors over the course of my ownership, anyway. That track shouldn't be the be-all benchmark for brake longevity (as the guys torturing brakes there will readily tell us.)

I'm not trying to say 350's are equal in performance, but they're a heavily proven option.

Frick, I just bought a set of Deman rotors, and they last about a year. Even at 28lbs, they can't weight much more then DEman/Protosport rotors, which are already boat anchors. Not sure what to make of the warning

TRAKCAR

Nonsense. I have dimpled now, what would be wrong with it??

M3EvoBR

Erik,

Deman are Cayenne rotors machined. I also use them on my non-cheater car.

Erik

yeah, I know. How much are Cayenne rotors at the dealership without the slots? and which ones do we need. Is it 2004 Cayenne S. ?

p.s. which car is your non-cheater car. I've never seen that one yet. You buy a new one ?

Since we're completely derailing Randy's thread at this point, might as well keep going


I saw that warning on the ATE rotors as well. I don't think that is a warning from ATE. I think that something specific to the site. I went to ATE's site and couldn't find such a warning.

So which Cayenne Rotors (year, model) are the direct replacement for .1 GT3 steel rotors?

I don't necessarily have a problem with the rotors being heavy. If anything, it will make for a better heatsink to keep things cool. Not to mention I don't have any sponsors hounding me over podium finishes

This is pretty cool that there are so low cost rotor options out there.

I had no idea the PCCB were larger, and subsequently that much more complicated with regards to changing rotor material options. That sucks...

M3EvoBR

dealership, I don't know but I can check it, and also how much machining would cost to do the same work, I bet that with the ATE or similar good quality rotor, we will spend around 250.00 for a machined set (out of the dealer).

On the low powered GT2, non cheater car.

M3EvoBR

I think is 2006 or so cayenne S, I'm not working Today, so I don't have it here in this comp. I'll send you the PN tomorrow.

deputydog95

You can get the ATE for $91 each here: http://www.imgt3performance.com/prod...d-front-rotor/

Probably end up costing around $220 shipped since they are so heavy. Sounds like a good opportunity to you use your shipping account

I also looked on Tirerack. If you look at the 2004 Cayenne S with 350mm brakes, the cost for what I'm assuming is the same ATE slotted rotor as the link above is $130 plus shipping.

Hmmmm...

M3EvoBR

Pretty much the same thing. Don't bother with shipping. I can buy them from my supplier with free shipping to me. What I said about the 250.00 would be regular rotors, and we send them out to be slotted

deputydog95

Is there any advantage to using the cayenne rotors and getting them machined vs the ATE rotors which are already machined?

M3EvoBR

to be honest I'm not a 100% sure, but the pattern on the ATE's are different than we use on the Deman.

deputydog95

Well, here's the price for the 2004 Cayenne Rotor. $270 at suncoast. That's pretty cheap considering the OEM fronts are $660 each from suncoast.

I don't have the foggiest about who could do the machining, what it would cost, or what pattern you should use though.
