The only issue with those track systems is that Sportsrack will not certify them for the full 150 lbs that the rack can hold. Only 75! This is because the roof material on the E is rather flimsy to attach the rack to.
I had the same tracks on my pickup canopy and when I went to sportsrack looking for options for the E, this is what the manager told me...

There are some pics of my set up mixed in here:

Ive got plenty more...ask if you'd like to see them...

They're just bolted right into the roof. There's no stabilization under the roof material at all. Go out and push down on your Es roof right in the middle...it just bows under even one hand pushing on it. This leads to torsion stress when you have an uneven load on your rack...hence Sportsrack's hesitation.

There's no need to remove the headliner...they use self tapping screws...
