AJ, the first day I loaded it (before the trip to NY) I loaded pretty far forward on the trailer, and our sport was pretty sacked out. I drove about 30 miles like that and didn't have any issues running, but I felt like it was too far forward.
When we went to NY I believe I loaded a bit too far back on the trailer, so it did sway a bit on the trip out. I'm going to try and find a balance between the two positions for the ride home. The tough part is because of the way I have to tie the car down (hooked to the frame in front and through the wheels in the rear) it's not as simple as adjusting the straps once it's on.
I may also give an anti sway and or load distributing hitch a try.
