The Thule roof bar kit for an E90 BMW comes with 108cm long bars. As seen here http://www.roofbox.co.uk/scripts/rbvehsel4.php?emulate=roofbar&query=4632&vptype=311659&brand=Thule
The Noddy question is, will the bars fit in the boot of the car, preferably neatly parallel to the opening and not diagonally across the boot, sitting on wheel arches?
