If you DIY and replace the brake pads often (or as needed), I believe you dislike the awkwardness of OE caliper's close top and well miss that open top convenience
This is how you replace a brake pad. Note the caliper is on our work bench and it can be turned to any way we want just to get the pad in. Imagine you have to detach the caliper from the spindle and it has a hard line attached, and work under the fender.
Spring must be in first
Then pad in, this is where the struggle is...
We have the caliper on bench with screw driver, after prying and pushing we thought it's done...
But take a look at this - The hold down spring is tapered, so after all that we still mis-align the spring to the pad nub...
With RB calipers pad "check" and "change" is so easy; 2x M6 pad bolt, and 1xM10 center bolt is what you have to deal with.
They cost only about 1/4 of pccb, better yet you don't have to wait for weeks or months from Porsche dealers - We stock them for the same day dispatch - guaranteed.
Buy from GM dealers and replace the discs yourself, or purchase complete new assembly from us then send the used rotors back later for core (hat) credit.

RB makes CCM brake more affordable and keep your maintenance cost in check so no more fear of replacement costs and save more money than standard iron brakes in the long run.
No rust, no dust, no fear brake that your 991 deserves.
John J - A Mustang GT350R track driver has found RB CCB rotor on sintered brake pad, replacing his OE iron rotors and pads, to be the optimal track set up that provides a "bullet proof" performance with lasting durability.
Carbon Ceramic Brakes - They're on!
It's time for an update on the CCB's. After running them for three track days and four months of highway and city service, I wanted to give the folks who wondered about my sanity an update ;-).
It turns out that I'm sane. I have to say that I put these on with some trepidation - the internet knowledge base said they would be fragile, that they couldn't handle track use and they'd be nothing but an expensive headache. My experience is the EXACT OPPOSITE. I love them. I'm never going back to iron rotors. These things are that good.
First, for track work, they are flat-out phenomenal. I've run them with both RB sintered pads and with Pagid RSL-29's. To help with thermal management, I put the Cooltech brake duct completion air deflectors on and I used titanium shims to protect the brake calipers. After my three trips to the track, I still have healthy caliper piston dust boots and the ATE Typ 200 fluid worked fine. Now, I could have upgraded the stock Brembo calipers with RB's stainless pistons and high temp seals and used Castrol SRF. That would have given me even more thermal capacity, and for racing you'd want that, but for me as a casual track day guy, I wanted to see if that level of prep was needed, and it wasn't.
The sintered pads are a new product and they're "streetable" in the sense that you can run them all the time if you want to, but they're a bit noisy. As for bite, they've got the bite of a tyrannosaur. Mu is around 0.60 and it's immutable. Same brake feel from cold to glowing hot. Most racing pads have a mu curve that you ride up and down as the brakes heat up and cool down. These things are always the same. As for dust and wear, well there's no dust and almost no wear. After three track days, the total pad thickness (two pads pressed face to face) had gone from 34.0 mm to 33.6 mm. I'm not particularly hard on brakes, but it looks like those pads will last a long time. And what's really interesting about the sintered pads is the transfer layer (see photos in this thread). Basically, the pad lays down a metal layer and that becomes the friction surface for braking. So, not only do CCB rotors outlast iron rotors with composite pads, with sintered pads, the metallic transfer layer renews itself as you use the brakes. So, the long-lasting rotors will last even longer.
One of the criticisms of CCB's in the past has been poor modulation. My experience with sintered pads and with the RSL-29's is that they're just as easy to modulate as any other brake system. Now, the high-mu sintered pads give you a lot of braking with moderate pedal pressure, but once I got used to the sensitivity, I stopped thinking about it and got on with driving.
If you want to know more about racing with CCB rotors, Google "David Donohue Pikes Peak brakes" and you'll find videos (one is on the DSC Sport Suspension website) showing David Donohue's run up Pikes Peak in this year's hill climb event. He's Mark Donohue's son, by the way. Anyway, the Google search will turn up a review that David wrote and posted on a forum (that's why I didn't provide the link) about CCB brake performance with sintered race pads on the Pike's Peak race car. Apparently, he likes them too.
The Pagid RSL-29 pads are approved by Pagid for CCB track use. That means they don't crumble when they get hot as some composite pads are known to do. They have less bite than the sintered pads, and they work great too. They are still on the car, and after a couple of months of driving around town with them, they're remarkably good as a street pad. Super quiet, good braking and virtually no dust. Another winner.
I also ran the OEM GT350 Ferodo pads for a couple of weeks just to see what happened. They worked fine - they were a bit dusty, but nothing like they are on iron rotors. I didn't take them on the track, and I don't plan to. I've got everything I need with the RSL-29's and the sintered pads.
So that's the update. This was one of two rewarding upgrades I did on my GT350 this year. The second one is the DSC Sport Magride controller. It's amazing too, and together the two upgrades really change the driving experience.
I noticed that CCM disc set prices took a $1000+ jump in the last few months, and Black Friday discounts?
Puck kits with blue high temp seal deals would be appreciated too, love your stuff!
Thank you

What isn't so clear is the question are there XC-40 sintered pads for 991 GT3 application.
If you follow the brake guide it never shows any sintered pad for the CCMs on 991 GT3/RS cars but it is mentioned in the forum
