⚙️ Requirements to Run This Setup
BMW M Performance / M3-M4 Front Calipers
The 380mm discs are designed to work with Brembo 4-piston calipers found on the F8x M3/M4 or M Performance kits.
Your existing 340mm calipers cannot be reused, as the offset and pad sweep are different.
Suitable Brake Pads
You can use M3/M4 or M Performance brake pads compatible with the calipers you are fitting.
Choose pads according to your driving style (OEM, fast road, or track).
Compatible Brake Lines (Optional but Recommended)
OEM lines can be reused, but stainless steel braided hoses are recommended for improved pedal feel and durability.
These will fit behind OEM 18" alloy wheels with a 12mm spacer
