MovIt Carbon Silicon Carbide Rotors as PCCB Replacement?

Email or IM me for current situation if you are thinking of giving them any business.

Ok- update. MovIt and I patched things up. They addressed my issues and we are moving forward again in positive fashion and I give them full credit for being willing to step-up and address the challenges we had.

I will post a full review in a few more weeks but I can say the direct, drop-in replacement MovIt Carbon/Silicon/Carbide rotors have proven durable and a greatly superior to the OE PCCB rotors. After 15 track days they show no obvious wear and pedal modulation remains much better compared to PCCB. Furthermore pedal feel remains consistent throughout a full track session.

At this point it does seem as though this is the "Holy Grail" of rotors: non-wearing, excellent pedal feel and modulation. A lifetime rotor.

A full kit is still in progress, delays are due to testing, redesign and refinement of the kit. But the OE sized replacement rotors are showing to be bulletproof under very heavy use. I will be testing an oversized, 396mm kit as well within the next few weeks and will of course report on that when I have some experience.

Peter, I am sorry things are turning for the worse. Be patient, it may turn back around again; well at least I sincerely hope so.

That's great. Tom sure seemed very accommodating. I just cant afford the price. I am converting to steel oem and using the pagid yellow.

I am glad MovIt is cooperating, I hope the experiment keeps its positive spin.

I've been driving a Cayman R with PCCB for a week and I can't believe how much bite and consistent modulation those brakes provide. Too bad I'd be afraid to subject them to track use, because of the potential cost of rotors.

MovIt update. Using OE sized carbon/silicon/carbide friction discs only, (not the calipers, not the available oversized rotors) I can report the following based on 15 track days (30-35 hours of race style usage on GT2/3RS :

1. Using a digital caliper there is no measurable wear of the friction disc. None. Zip. Zilch.
2. The original machine marks and crosshatch pattern is still visible on the surface.
3. The surface remains very smooth to the touch.
4. The "phonograph" style grooving is visible to the eye but not felt by the finger. Cosmetic only.
5. Pad wear time and tapered wear pattern is essentially the same as OE, perhaps a 20% improvement. Still require you to flip after a few track days. No billet calipers (yet) equal a tapered wear pad, just that simple.

Because these friction discs are so bulletproof, you can wait a bit longer than pad friction material being at thickness of backing plate rule of thumb for pad replacement. I am advised the friction disc will not be damaged (!) in the event of backing plate contact but not a game I am willing to play to get "one more session" from a set of pads. At least you are not playing with a $$$$ catastrophe as with the OE PCCB friction discs.

As far as friction disc (rotor) the MovIt Carbon/Silicon/Carbide product does appear to be a truly lifetime solution to worn friction discs (rotors).

I will be installing their new full system including billet calipers for GT3/GT3 fitment in approx 6 weeks as well as a massive, direct-replacement, rotors only, 396mmx40 front rotor and 380mm rear rotor kit (without the MovIt Billet Caliper) and report on those. Based on the superb performance of only an OE sized friction disc, the result should be "monumental".







The markings you see are cosmetic, surface is smooth to the touch.




Smooth as a baby's butt!



That is original honing marks/crosshatch you see there-



More original honing marks

Pete, thanks so much for the updates on these rotors. I look forward to your testing and reviews and am lovin this website too. I'd have these MovIt rotors in a heart beat but I'm afraid to even bother the MovIt rep and ask what the price is and if they even make these as a replacment for a 997 Carrera S...same sizing as 996 Turbo.

Good info trackrat.

Thanks for the update. Still such a pricey option. I converted to steel on my 11 rs. I will be at road america this weekend to see the difference. Not sure what to expect.

Hey, we met Stuelly today.

Great group of guys, but they forgot to bring beer to the track and we ran out of alcohol..
We must be circeling at the opposit side of the track because I have not seen many RS around me yet.

My Carrera GT PCCB rotors are starting to look pretty crappy and the pads make a scuffing noise when I apply the brakes in situations that are quiet enough to hear them. My Porsche dealer says I might get a few more track events out of them, but they are showing surface de-lamination and won't last forever. This is somewhat off-putting since the parts quote is circa $22,000 for 4 rotors, then it is PLUS installation.

I have been having an e-mail conversation with Mov'It USA and it seems they have a GT2/GT3RS-based solution that includes rotors, calipers, pads and a special emergency brake caliper for the rear to fit the Carrera GT. Their price is North of the OEM rotor replacement, but not too much for their whole caboodle.

My question for any users of Mov'It ceramic brake systems is how they feel and respond on the street. Do they behave in a normal way, or would you who have them only recommend them for the track?

"Perfect"

Once the pads are bedded, it feels great on the street. As good or better than OE PCCB. I have them on Spyder and GT3RS and love them. Wet/dry/track/street- all excellent.

Caution: Do not ever use the P50 Green PCCB pads with the MovIt rotors! Terrible brake feel. P50's are bad for street for OE PCCB as well and I would personally never use them on any PCCB system for any situation, even tracking (and I have 4-5 P50 sets used under my belt).

That's very encouraging. I might just have to "update" my Carrera GT with better brakes!

I'm going to a 918 event in Weissach in a few weeks and I'll try my best to coax some more brake info out of their engineers.

I bet that will be a special event Mike, and you tell us all about it

Do you have one on order?

OK, I'm back from the 918 event.

During our tour of the Weissach work shops I cornered a high-up chassis development engineer and asked him if the 918 PCCB brakes were going to be more durable than the ones on the Carrera GT. He had a quizzical look on his face so I told him about my track experiences.

When we were absolutely out of earshot of anyone else he said that even though PCCB is probably a "forever" rotor on the street, they are wear parts on the track.

I just ordered Mov'It rotors for my Carrera GT.

LOL, of course, typical big corp with new product, cannot blame them of course, very competitive market. At least you may be able to tell us how much fun it is
