Dinan Big Brake Kit BMW

The Dinan Big Brake Kit is a high-performance brake upgrade (big brake kit, BBK, or brake conversion) for BMW vehicles. It replaces the factory calipers and rotors with larger, stiffer components. The result is stronger stopping power and more consistent pedal feel. It also resists brake fade better during spirited street driving, canyon runs, and track days.

Key Features:

• Multi-piston aluminum calipers, either billet or monoblock depending on the kit. They give strong, even clamping force.
• Oversized rotors with lightweight aluminum hats to improve heat management and cut unsprung weight. Current kits use 2-piece semi-floating rotors with curved cooling vanes.
• Stainless steel brake lines, with DOT/TUV-approved Goodridge lines in the Dinan by Brembo kits. They give a firmer, more responsive pedal.
• Dinan-spec brake pads. Dinan designs them to work with BMW brake wear sensors, so the factory safety system stays functional.
• Mounting brackets and installation hardware included for a bolt-on installation.
• Dinan-approved front-to-rear brake balance, with matched front and rear kits available.

Dinan has tuned BMWs for decades. Each kit is engineered for specific BMW chassis and built with premium machining and quality control. Kits are available in different caliper finishes and for different axles and model generations. Choose the child item that matches your application.
