• 2022+ Lotus Emira (rear axle)
When the time comes to service your Lotus Emira’s rear brakes, the Girodisc D2-388 replacement rotor rings restore full performance without the cost of replacing the complete assembly. Designed to mount directly onto your existing A2-388 hats, these rings deliver the same high-carbon iron strength, curved-vane cooling, and track-ready performance as your original Girodisc setup.
Durable, high-performance replacement rings
Each ring is machined from Girodisc’s proprietary high-carbon iron alloy, engineered for thermal stability and durability under repeated heavy braking. The 48 curved internal vanes work like a centrifugal pump to draw air through the hub, keeping temperatures down during demanding street or track use. Because the hats are fully reusable, you only need to replace the rings — saving money while keeping your braking system race-ready.

Ferodo Brake Pad Compound DS3.12
The DS3.12 brake pad compound is the latest evolution in Ferodo's incredible DS line. Sports cars today have more of everything: more horsepower, more sophisticated aero, higher curb weights, and stickier tires. These attributes place serious demands on a vehicle's brake system.
Ferodo 11 FRP3152GB-N Comparison Chart
The Ferodo DS3.12 is the modern pad compound designed from the start to explicitly handle those demands. Out of all the pad compounds we've ever tested, from all manufacturers, the DS3.12 shows the flattest torque curve across the broadest temperature range. That means on every turn, on every track you drive, on every lap, your brake pedal is going to feel almost exactly the same. This gives you tremendous consistency and repeatability.
Ferodo 11 FRP3152GB-N Coefficient of Friction (Mu) Chart
The DS3.12 has a higher mu (µ) than Ferodo's other compounds, so not as much pedal pressure is required to initiate the desired response. It is also un-fadable, showing no drop in performance at any temperature your brakes will ever see. In dyno testing, the Ferodo DS3.12 has shown superior wear rates compared to the other Ferodo compounds, while remaining kind to brake rotors.
Ferodo 11 FRP3152GB-N Temperature Chart
We believe the Ferodo DS3.12 will become the gold standard to which other race compounds will be compared.
