Dinan D230-0391 by Brembo Replacement Rotor Set Front Slotted 355x32mm

The Dinan D230-0391 by Brembo Replacement Rotor Set is a direct-fit front rotor replacement for the Dinan/Brembo big brake conversion system. Measuring 355 x 32mm, these silver-plated slotted rotors are engineered to restore full braking performance to your Dinan big brake kit with a precise, factory-matched fit.

Developed through extensive street and track testing, the Dinan by Brembo brake program is built to deliver maximum stopping power while avoiding common pitfalls of aftermarket brake upgrades — including unbalanced proportioning, poor pedal feel, and excessive noise. These replacement rotors uphold the same performance standards as the original kit components.

Key Features:

• Front rotor set — 355 x 32mm slotted design
• Silver-plated finish for corrosion resistance
• Slotted rotor faces for improved heat dissipation and bite
• Includes new installation hardware
• Left and right rotors included (bells/hats not included)
• Rotors cannot be resurfaced — replace when worn
• Compatible with BMW chassis codes: E39, E46, E82, E88, E90, E92, E93
• Legal for use on emissions-controlled, non-emissions-controlled, and racing vehicles

These rotors are intended as a replacement for the rotor faces only — the original aluminum bells/hats from your existing Dinan/Brembo setup are retained. Dinan's Lower Control Arm Monoball Kit is recommended during installation to minimize brake shimmy. Note that in most applications, aftermarket wheels may be required to provide adequate clearance for the oversized rotor diameter.
