We had an 8:05ADR in June and we finished up with enough time to walk over to rope drop. Make sure you ask for the check early so that you can pay and finish up your meal. Paying always seems to take longer!!!
The only think I didn't like is that you are at the rope drop at World Showcase, so it takes you longer to get to Soarin than the people walking from the main entrance. Although you can probably get to Test Track quicker than the folks at main entrance.
Have a wonderful meal!!
