How Much Does McLaren Carbon Ceramic Brake Disc Replacement Really Cost? (And What McLaren Owners Are Doing About It)
McLaren carbon ceramic brake disc replacement is the bill most owners never see coming. You're enjoying the car, the pedal starts to shudder under braking, and a specialist tells you the discs are done. Then comes the number.
This article breaks down what a replacement set really costs, why the discs wear the way they do, and what your options look like in 2026.
Why McLaren carbon ceramic discs cost so much
Many McLarens, from the 12C through the 765LT, are fitted with carbon ceramic discs from the factory, either as standard or as an option. They're a carbon fiber and silicon carbide composite. Compared with iron, they run cooler under heavy braking, weigh far less, and hold up better to repeated hard stops.
The catch is what happens when they wear. You can't skim a carbon ceramic disc back to size like an iron rotor. Once the friction layer is gone, or the disc is cracked or damaged, the disc gets replaced. The material is expensive to make, volumes are low, and a full set is a real event, not a routine service item.
What genuine McLaren discs cost
Pricing varies a lot by supplier and model, and we haven't found a published dealer price list, so treat these as reference points rather than quotes. In October 2026, new genuine carbon ceramic disc sets for the 720S family were listed at roughly $9,700 at one US supplier and £13,500 at a UK supplier, for the discs alone, before installation. Pads, labor and shipping come on top.
For a car that's a track-day weapon, a maintenance item at that level changes the economics of owning it.
When McLaren carbon ceramic brake disc replacement comes due
Every car and driver is different, so we won't pretend there's a magic mileage. The usual signs are vibration through the brake pedal, noise under braking, visible cracking or chipping, or a measured wear figure outside McLaren's spec. Hard track use and the wrong pad compound are the usual culprits. If any of that sounds like your car, get the discs measured before they get worse, not after.
Your options
You've got two sensible routes. One is genuine McLaren discs, which means the factory part at the highest price. The other is aftermarket carbon ceramic built to the same fitment.
Fitment is the easy part. What separates one aftermarket disc from another is what's inside it and who stands behind it.
Why the disc's internal structure matters
Most buyers compare price and fitment and stop there. What actually decides how a carbon ceramic disc ages is what's inside it.
Gen 2 construction mixes short, chopped carbon fibers into the silicon carbide. That works, but short fibers mean more interruptions in the structure.
Gen 3 construction, which is what we build, runs long continuous fibers through the disc in a 3D bonded structure. The idea is a stronger structure, heat that spreads across the disc, and a friction layer that lasts longer under repeated hard stops.
So before you compare prices, ask what fiber structure you're actually buying.
Triton's McLaren carbon ceramic brake disc replacement range
Our Gen 3 McLaren discs are built as direct replacements for the factory carbon ceramic discs, with no caliper or hardware changes. They're for cars fitted with factory carbon ceramic discs, so if your car has been converted to iron brakes, email us first.
There are two sizes across the range.
For the 570S, 650S, 675LT and MP4-12C, the discs are 394mm by 36mm up front and 380mm by 34mm at the rear:
For the 720S, 600LT, 765LT and GT, they're 390mm by 36mm up front and 380mm by 34mm at the rear:
One thing for 765LT owners: if your car has the optional MSO brake package, it runs a 390mm rear disc instead of the 380mm rear listed above. Email us before you order and we'll confirm the right disc for your car. There's also a general McLaren page that covers both families.
Pricing starts at $6,298 on the 720S, 600LT, 765LT and GT, and at $6,898 on the 570S, 650S, 675LT and MP4-12C pages. That's thousands less than genuine discs. Lead time is about 45 days, so order before your discs are on their last legs. Browse the full carbon ceramic range →
Built for the long haul
Carbon ceramic discs are a long-term purchase, so who you buy from matters as much as what you buy. Here's where we stand.
We've been supplying McLaren owners for years, not months. The reviews on our McLaren pages go back to 2023, and every one of them is five stars. Carbon ceramic is also only one part of what we do. Triton builds forged wheels, iron brake rotors, big brake kits and exhaust systems too, so the business doesn't rest on any single product. We're based in Texas, and every disc carries a one-year, 36,000-mile warranty. We built Triton to be here for the long haul, and your discs should have a company behind them that is.
Frequently asked questions
Do your McLaren carbon ceramic brake disc replacements work with my existing calipers?
Yes. They're designed as direct replacements for the factory carbon ceramic discs, with no caliper modifications. Send us your model and year if you want us to confirm before you order.
My 765LT has the MSO brake package. Will your discs fit?
Standard 765LTs take the 380mm rear disc on our page. MSO cars run a 390mm rear, so email us before you order and we'll confirm the right disc for your car.
Do I need special brake pads?
Yes. You need pads made for carbon ceramic discs, since pads made for iron brakes aren't suitable. Pads are sold separately on our McLaren pages, so ask us which compound suits your car and how you drive.
How is Gen 3 different from factory discs?
Factory discs use chopped carbon fibers. Ours use long, continuous fibers bonded in a 3D structure. That's a different internal construction, and it's the reason we built the range around it.
How do I choose between aftermarket carbon ceramic discs?
Start with the fiber structure, then confirm the disc is a direct fit for your exact model and year with no caliper changes. After that, ask who stands behind it: how long the maker has been supplying discs, what the warranty covers, and whether you can still get a replacement set a few years from now.
Will Triton still be around to support my discs?
Yes. That's how we've built the business. We've been supplying McLaren owners since 2021, carbon ceramic is one product line among several, and every disc carries a one-year or 36,000-mile warranty from a Texas-based company you can reach directly.
What warranty do the discs carry?
One year or 36,000 miles, whichever comes first, against manufacturer defects.
The bottom line
A full set of genuine discs is a big cheque, and every owner of a carbon ceramic McLaren writes it at some point. You can pay McLaren's price, or you can fit a Gen 3 disc built for your car for thousands less. If you go that way, check the fiber structure, confirm the fitment, and buy from a company that's built to be around.
