This is what i ordered for my BMW X5 in the end:

Thule WingBar Edge 104 cm roof rack crossbar 1-pack black | 721520
Thule WingBar Edge 95 cm roof rack cross bar 1-pack black | 721420
Thule Flush Rail Edge foot for vehicles 4-pack black | 720600
Kit 186007

Sorry, I just checked my records and previous orders. I was wrong, i had to also order separately the feet and edges. But as suggested, check the Thule website and enter your vehicles make model and year of manufacture. My vehicle needed the large bar at the front and the medium at the rear. I ordered the bars separately.
I ordered initially what you have specified and then returned them and re-ordered. It is complicated at times unfortunately.

As suggested above, check the Thule website and enter your vehicle's make, model and year. The M/L are 104cm/95cm, and are for the front bar and rear bar to allow for the narrowing shape of the roof. The set I ordered as you have specified above included the mounting kit, 4 feet and the 104/95cm bars.

Hello, it still needs mounting feet, but as I have returned this item I unfortunately cannot say which ones. It depends on the type of roof rack. Mfg
