If you want to fit x5 m front / rear bumpers you also have to get the X5 M or 'M sport' wheel arch extensions and side skirts (they are the same)
On my 2011 X5 40d I have installed the full BMW performance bodykit custom painted with silver alu details, aluminium window trim, X5 M aluminium roof rails, Eibach springs (-50mm front -35mm rear), H&R spacers (12mm front 20mm rear), thicker anti-roll bars (29mm front 24mm rear, solid not hollow like OEM), K-mac camber plates on order, 50i exhaust and bumper cut-outs, X5 M50d mirrors and painted plastics, F15 LED fog lights, X6 LCI titanium kidney grills, open bumper mesh grills in silver, BMW Individual wood steering wheel matched to bamboo trim, bamboo gear selector, LED interior lights, DPF delete & remap, aftermarket anti-theft system (X5 can very easily be stolen, I strongly recommend additional protection, already had one stolen on the past) llumar ceramic window tints on all windows (including windshield and pano roof)... a few other small things as well
