Girodisc 2-Piece Floating Rear Rotors for BMW E9X 335i & 335xi (A2-114)

Girodisc Rear 2-Piece Floating Brake Rotors – BMW E90, E91, E92 & E93 335i/335xi

Upgrade your BMW's braking performance with the Girodisc A2-114 Rear 2-Piece Floating Rotors, engineered specifically for the BMW E9X 335i and 335xi platform. Designed as a direct replacement for the factory rear brake discs, these lightweight performance rotors offer improved heat dissipation, reduced unsprung weight and exceptional braking consistency for both fast road driving and track use.

Unlike oversized brake conversions, Girodisc's two-piece rotor system retains the factory rear calipers, parking brake and ABS functionality while delivering the performance benefits of a motorsport-inspired floating rotor design. Installation is completely bolt-on with no vehicle modifications required.

Lightweight Motorsport Construction

Each Girodisc rear rotor combines a precision CNC-machined 6061-T6 aircraft-grade aluminium centre hat with a proprietary high-carbon cast iron friction ring. This premium construction reduces rotating mass while improving thermal stability under repeated heavy braking.

The internal curved directional vane design actively draws cooling air through the rotor, helping to reduce operating temperatures, minimise brake fade and maintain consistent braking performance during demanding driving conditions.

Fully Floating Rotor Design

Girodisc's floating rotor assembly utilises 10 high-strength alloy steel drive pins that securely connect the rotor ring to the aluminium hat while allowing controlled movement during heat expansion.

Key benefits include:

• Allows the rotor to expand naturally under high temperatures
• Reduces thermal stress and rotor distortion
• Improves brake pedal consistency
• Helps the rotor self-centre within the caliper
• Provides dependable braking performance under repeated heavy use

To eliminate the rattling commonly associated with floating brake rotors, Girodisc incorporates specially designed anti-noise spring hardware that keeps the system quiet during everyday driving while allowing unrestricted thermal expansion under load.

Serviceable Two-Piece Design

One of the major advantages of the Girodisc rotor system is its modular construction. When the friction rings eventually reach their service limit, they can be replaced independently while retaining the original aluminium hats. This significantly lowers long-term maintenance costs compared to replacing complete rotor assemblies.

Whether your BMW is used as a daily driver, weekend performance car or dedicated track machine, Girodisc's serviceable design provides lasting value without compromising performance.
