Well you know these weren't going to be cheap. I guess it's cheaper than two piece aluminum hat rotors and certainly cheaper than carbon ceramic rotors but a lot more than stock rotors for our S197 cars.

With a discount, those rotors aren't too bad. I'm expecting them to hold up much better than the S197 rotors. The pads should actually net out cheaper than the Hawk pads I've been running. Pleasantly surprised.

Have you found the tech manual on how to replace them yet?

Yes hopefully Ken and team at KNS Brakes will be able to get us a better price. @KNS Brakes

I'm also expecting the rotors and pads to last longer than the ones on our current cars. The rotors are also thicker at 35mm like my Stoptech spec Mustang setup. They should dissipate heat well.

It will also be interesting to see if the pads are as good as the engineers told me and I think they will be. Pads are a personal preference item and I suspect you're be back to your Hawks after the stocks are worn. The car coming stock with DOT 4 brake fluid tells me these will be serious stoppers right off the showroom floor.

Yes they are but don't be so sure. I'm hoping they'll bite hard, but something tells me they'd squeal like a Burlington Northern if they do, and that usually doesn't go over well on a street car. Maybe it's a magic new formula

Not that bad, IMO. Hopefully they last longer than the S197 stuff.

I think it's going to last longer than the S197 stuff that's for sure.

Not sure you'll be able to swap to a different rear rotor after looking at this photo. The parking brake(s) are a drum setup using the inside of the rear rotor as the drum.

My links in the first post keep breaking and I can't find the parts anywhere else but go to www.fordparts.com and put in the part number. With the typical 15-20% discount these will be fine. Way cheaper than a CC rotor.

195.86 ea front rotor at Tousley (Auto Nation). Best thing Ford did was stick with Iron rotors! This is a really good deal for the track user. Full floating 2 piece for $400 a pair is awesome.

Wow that's a great price. I was paying around $140 for one-piece OEM rotors on the Boss.

I agree. All I hear at the track are how the Porsche and Ferrari guys wish they didn't have them due to costs. Ford gave us an awesome solution.

I buy mine from CJ Pony, $50 per rotor front and rear...$200 for all 4

After hearing @StigsBaldBrother comments about blowing through his pads after two track days I went back and looked @Black Boss pad photos and remember thinking the pads looked a bit thin when I saw them at Track Tour. According to the specs I have the GT350 front pads are approximately 10mm thick. AFAIR the pads for the Boss were 14-15mm thick and the pads on my Stoptech kit were 17mm thick. The race Brembos are 25mm thick. Can anyone verify the pad thickness on the GT350? I'm just curious more than anything.

Stock GT350 front pads are 9.5mm Thick. Both Carbotech and Pagid Boss pads are 10mm. So just 5% thinner, but would have preferred thicker.....

I wonder if the stockers are also a very soft compound to cut down on noise (as are most stock brembo pads).

Does anyone offer a Carbon ceramic rotor for the GT350/R? It would be nice to see someone offer this as a direct replacement over the stock aluminum/iron version for a weight savings standpoint. Do other cars that use the Carbon ceramic rotors have the rear parking shoes or do they use a separate parking caliper or is it all within the rear brake caliper?

There are not a lot of aftermarket parts available yet. I'm not familiar with other vehicles using the same drum within the rotor but I'm sure they are out there. I'd be more interested to see if a quality two piece race rotor like Stoptech or Girodisc will save weight over the stock front rotors. My guess is there is a 2 lb savings per rotor.

I spoke to Mike at Girodisc the other day and he said they will make a 2 piece rotor for the GT350 but it will be slotted. I asked about weight he said it "may" be lighter then stock but since the stock ones already have a aluminum hat it's gonna be marginal. We'll see. Would any of you be switching to this rotor even if it's not any lighter in weight?

Not worth it for me, im guessing any aftermarket rotor will be almost 2X the cost of an OEM unit. Even if the rings become replaceable, the replacement ring will likely still cost more than complete oem unit and then you have to take the time to disassemble and reassemble

Since the oem hat is cast, there can likely be some weight savings going to a machined billet hat, but not sure if it will be significant

Different angle, but I'm noticing much better bite after getting a few miles on the car. These pads definitely need to be bed-in before they start to really work.

I highly doubt much if any weight will be lost from the aftermark rotors. The only thing that annoys me about the stock rotors is the rust around the edges. It makes a mess on the inner wheel
