McLaren brake upgrades come down to one hard truth: the factory carbon-ceramic discs on cars like the 789-hp Senna and the 562-hp 570S are magnificent on the road but ruinously expensive to replace once you start using them on track. A single OEM carbon-ceramic rotor can run well into five figures, and McLaren notes each Senna ceramic disc takes roughly seven months to manufacture. GiroDisc solves this with a two-piece slotted iron conversion – a serviceable, track-ready rotor that bolts to the factory calipers and cuts long-term brake costs dramatically. This guide compares the GiroDisc lineup for the McLaren Senna, 570S, 570GT and 540C, from $1,500.00 to $2,212.50 per rotor.
Our Verdict
The GiroDisc McLaren Senna Iron-Conversion rotors are the smartest brake spend for any track-driven McLaren.
At $2,212.50 per rotor, the Senna front kit replaces a fragile, near-irreplaceable carbon-ceramic disc with a floating two-piece iron rotor whose friction ring can be renewed for $929.25 – a fraction of OEM CCM replacement. Same-day answers on fitment from our Tampa, FL shop.
Shop Our Top Pick →Why Upgrade the Brakes on a McLaren Supercar?
The reason to upgrade McLaren brakes is cost of ownership on track, not a lack of stopping power. McLaren's Ultimate and Sports Series cars already stop hard: the Senna pairs 390mm front / 380mm rear carbon-ceramic discs with 6-piston front and 4-piston rear monobloc aluminum calipers, and it will haul down from 124 mph in under 100 meters. The problem is what happens after a dozen hard track sessions. Carbon-ceramic (CCM) discs are brilliant for street durability and unsprung weight, but they glaze, chip and eventually wear under sustained racetrack heat – and replacing them through McLaren is one of the most expensive consumables in the supercar world.
That is the exact gap the GiroDisc two-piece iron conversion fills. Iron rotors are consumable by design: you can run them hard, replace the friction ring when it is done, and keep the aluminum hats and hardware. For an owner who tracks a 570S or Senna, converting to serviceable iron can pay for itself in a single avoided CCM replacement. The trade is a small increase in unsprung mass and a bit more brake dust – a fair deal for a car that lives at HPDE and club days.

How GiroDisc Two-Piece Floating Rotors Work
A GiroDisc rotor is a two-piece floating assembly: a cast-iron friction ring mounted to a 6061-T6 aluminum center hat by a ring of stainless-steel drive pins. Anti-noise spring clips let the ring “float” radially a few thousandths of an inch, so the iron can expand with heat without coning, cracking or transferring stress into the hat. The result is a rotor that runs truer at temperature and resists the heat-checking that kills one-piece discs on track.
The friction faces are slotted rather than cross-drilled. Slots continuously de-glaze the pad and vent gas and dust without the stress risers that make drilled rotors crack under racetrack loads. Internal directional vanes pump cooling air from the center outward. Because the hats are aluminum instead of iron, the complete assembly is lighter than the OE one-piece casting it replaces, trimming both rotating and unsprung mass – the weight that most hurts steering response and ride.

Best McLaren GiroDisc Rotor Kits Compared
Every rotor below is a direct bolt-on that reuses your factory calipers and OE-size pads. The four CCM-equipped fitments (Senna and 570S/570GT with carbon-ceramics) convert the ceramic setup to serviceable iron; the 540C/570GT non-CCM kit is a 380mm iron upgrade with the correct spacers. Prices are per rotor, so budget front and rear pairs accordingly.

1. GiroDisc McLaren Senna Front Rotors – Best Overall
The Senna is McLaren's most track-focused road car – a 789-hp, 590 lb-ft, ~2,641 lb Ultimate Series machine that hits 208 mph. Its factory carbon-ceramics are exotic and effectively disposable once heat-cycled hard. This GiroDisc front kit converts each corner to a floating, slotted iron rotor you can actually afford to consume, and when the ring wears you renew just the friction surface. For any Senna that sees a road course, this is the single most sensible brake upgrade on the shelf.
2. GiroDisc McLaren Senna Rear Rotors
Convert the axle, not just one end. Pairing the rear rotors with the fronts keeps brake bias and pad temperatures balanced on track, which is exactly where a mismatched setup shows up as inconsistent pedal feel. Budget $4,425.00 for the complete Senna front-and-rear rotor conversion – still a fraction of a single OEM carbon-ceramic axle replacement.
3. GiroDisc McLaren 570S / 570GT Front Rotors
GiroDisc 570S/570GT rear rotor ($1,900.00) completes the Sports Series conversion.
The 570S runs a 3.8L twin-turbo V8 making 562 hp and 443 lb-ft, good for 0–60 mph in about 3.1 seconds and 204 mph flat out. Cars optioned with carbon-ceramics get the same disposable-disc problem as the Senna, just at a lower price of entry. This GiroDisc front kit ($1,995.00) and its matching rear ($1,900.00) convert a CCM-equipped 570S or 570GT to serviceable iron for roughly $3,895.00 an axle-set – the go-to move for a tracked Sports Series McLaren.
4. GiroDisc McLaren 540C / 570GT 380mm Front Rotors
Not every Sports Series car left the factory on carbon-ceramics. The 533-hp 540C and iron-disc 570GT run cast-iron rotors from new, and this $1,500.00 GiroDisc kit steps them up to a two-piece 380mm slotted front rotor with the correct spacers – more thermal capacity and a lighter, serviceable assembly without changing calipers. It is the most affordable entry point into the GiroDisc McLaren range.
5. GiroDisc Senna Replacement Front Rings
This is the payoff of the two-piece design. When the friction surface is worn, you do not buy a whole new rotor – you bolt a fresh $929.25 front ring onto your existing aluminum hats and hardware. Over the life of a hard-driven Senna, reusing the hats turns brakes from a catastrophic bill into a routine consumable, which is the entire economic argument for converting away from carbon-ceramics.
Track Pads for the Sports Series McLaren
Rotors are only half the system. On the earlier MP4-12C and non-CCM 570S cars running AP Racing CP7040 calipers, a proper high-temperature pad transforms feel and fade resistance. Two proven options ship in stock:
EBC's Bluestuff NDX ($202.90) is a fast-road and track compound with a high friction coefficient and strong initial bite, yet it stays civil enough to drive home. For owners who want a lighter-duty street pad, the Hawk MP4-12C HPS 5.0 front set ($152.36) is the value pick – more bite than OEM with low dust and quiet operation.

Iron Conversion: Pros and Cons
What We Like
- + Slashes track brake costs versus OEM carbon-ceramic replacement
- + Replaceable $929.25 friction ring – reuse the aluminum hats
- + Floating slotted iron resists heat-checking and glazing on track
- + Direct bolt-on: keeps factory calipers and OE-size pads
Things to Consider
- – Iron adds unsprung mass versus factory carbon-ceramics
- – More brake dust and a longer warm-up than CCM discs
- – Priced per rotor – a full conversion is a four-rotor purchase
Fitment and Installation Notes
Confirm your car's original brake specification before ordering: the Senna and CCM-optioned 570S/570GT take the “iron conversion” kits, while iron-disc 540C and 570GT cars use the 380mm upgrade with spacers. Because these are direct bolt-on rotors, installation mirrors a standard two-piece rotor swap – no caliper brackets or lines to modify – and a fresh set of pads plus a proper bed-in procedure is strongly recommended when converting from carbon-ceramics. Our Tampa, FL team can verify the correct kit by VIN and match it to the right track pad before you order, so you get one complete, correct package the first time.
Frequently Asked Questions
Are GiroDisc rotors a good upgrade for a McLaren Senna?
Yes. GiroDisc's two-piece slotted iron rotors convert the Senna's costly carbon-ceramic brakes to a serviceable, track-friendly setup at a fraction of OEM CCM replacement cost. Each front or rear rotor is $2,212.50, and the worn friction ring can later be replaced for $929.25 instead of buying a whole new disc, making them the most cost-effective brake upgrade for a track-driven Senna.
How much do McLaren GiroDisc brake rotors cost?
McLaren GiroDisc rotors run from $1,500.00 to $2,212.50 per rotor at NLP Performance. The 540C/570GT 380mm front kit is $1,500.00, the 570S/570GT CCM-conversion rotors are $1,900.00 (rear) and $1,995.00 (front), and the McLaren Senna front and rear rotors are $2,212.50 each. Prices are per rotor, so a full-axle conversion requires two.
Will iron rotors fit McLaren's factory calipers and pads?
Yes. GiroDisc rotors are a direct bolt-on that reuse the OE calipers and OE-size pads, with no bracket or brake-line changes required. The Senna and CCM 570S/570GT kits are engineered specifically to convert carbon-ceramic setups to iron, and the 540C/570GT kit includes the correct spacers for its 380mm upgrade.
Why replace carbon-ceramic brakes with iron on a supercar?
Carbon-ceramic discs are excellent on the street but wear quickly and can crack or glaze under sustained track heat, and OEM replacements cost well into five figures. Iron rotors are a consumable by design: you can run them hard, replace only the friction ring when worn, and keep the hats and hardware, dramatically lowering the cost of tracking a McLaren.
What is the difference between the 570S 'w/CCM' and 540C 'w/o CCM' GiroDisc kits?
The 570S/570GT 'w/CCM' kit is for cars originally optioned with carbon-ceramic discs and converts them to two-piece iron. The 540C/570GT 'w/o CCM' kit fits cars that left the factory on cast-iron discs and upgrades them to a 380mm two-piece slotted iron rotor with the correct spacers. Choose the kit that matches your car's original brake type.
Do GiroDisc two-piece rotors reduce weight?
Yes. GiroDisc pairs an iron friction ring with a 6061-T6 aluminum center hat, so the complete assembly is lighter than the one-piece OE iron rotor it replaces, cutting rotating and unsprung mass. Against factory carbon-ceramics, iron does add some unsprung weight, which is the main trade-off for the lower running cost.
