BMW 4 Series Brake Kit - Rear - Dinan - Slotted Rotors + 4-Piston Calipers - Black - '17-'20. A rear upgrade for 2017-2020 4 Series RWD with M Sport brakes, pairing black 4-piston calipers with slotted rotors.

Co-developed with Brembo, this Dinan rear system adds thermal capacity while preserving proportioning and pedal feel. It includes 345 mm slotted rotors with aluminum hats, black monoblock calipers, Dinan-spec pads that retain BMW wear sensors, Goodridge DOT/TUV stainless lines, and all brackets/hardware. Must be paired with Dinan/Brembo front brakes; backing plates require modification. Verify wheel clearance—many cars need aftermarket wheels; reference Brembo Gran Turismo. Review the caliper fitment and installation guides before ordering.
