Girodisc 380mm Iron Rear Rotors
Girodisc 380mm cast iron rear rotors for the McLaren Artura, a direct bolt-on replacement for the factory Carbon-ceramic matrix — the lightweight, high-temperature brake disc material fitted to the Artura from the factory. discs that works with the original calipers. The 6061-T6 aluminum hat and racing-spec cast iron disc are joined by a floating pin system that lets the disc grow with heat while staying quiet when cold, and self-centers between the pads. Once installed, only the cast iron disc needs replacing down the line — the aluminum hat is reused. Sold and priced in pairs.
Frequently asked
Does the Girodisc 380mm Iron Rear Rotors fit my Artura?
This listing is specific to the McLaren Artura. Exact fitment for your year, trim and options is confirmed on your free consult before anything is ordered.
What does the price include?
The delivered price includes the part from Fabspeed USA, freight to Australia, import costs and GST. Enter your postcode to refine delivery; the final figure is confirmed on consult.
How long until it arrives?
Every Fabspeed part is made in-house at Fabspeed USA with about a one-week production lead time, then allow another 3-4 days for delivery to Australia via UPS. That freight is already included in the price.
Do these work with the factory calipers?
Yes, no modification is needed — the disc bolts directly to the car and works with the original calipers.
What replaces the factory CCM discs?
A cast iron disc mounted to a 6061-T6 aluminum hat through a floating pin system, in place of the carbon-ceramic disc fitted from the factory.
Do I need to replace the whole rotor assembly down the line?
No — once installed, only the cast iron disc itself needs replacing; the aluminum hat is reused.
Who installs it?
Rennen Motorsport in Adelaide, or an authorised dealer near you. Fitting it yourself may also be an option depending on the part, so raise it on your consult; professional installation is quoted separately.
Is it covered by warranty?
Fabspeed products carry the manufacturer's warranty, supported locally through Rennen Plus as the Australian principal. See our returns policy.
Can I just buy this outright, or do I need to talk to someone first?
Every enquiry, whether it's one part or a full build, starts with a free consult. We confirm the exact spec for your car before anything is quoted or ordered.
