Cruz Aero Black Roof Bars for BMW 4 Series Grand Coupe / I4 G26. Sleek aero cross bar style without the ugly wings. These bars are perfect for roof boxes. The black looks much nicer than silver. Less than 3 years old and used once for a family holiday to Italy and have been stored in a dry garage. We did plenty of motorway driving with them and pleased to report no whistling or offensive noises. Because they’ve only been on and off once I’ve got all the instructions, bolts and tools required.
