Girodisc Replacement Rear Rotor Rings for Lotus Emira
D2-388 Vehicle fitment
• 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.
