In a bowl combine all of the spice rub ingredients and mix well. Cover the ribs in the spice mixture, making sure to massage the spices into the meat.
Place the ribs in a resealable bag and refrigerate for at least 1 hour or up to 3.
Combine all of the ingredients for the sauce in a bowl, whisk and set aside to let the flavors meld.
Preheat the grill to medium heat 350°F. If using a 3 burner grill, light only 2 grates (the middle and one side) leaving one off. If you have a 2 burner grill, light only 1 side.
Lay two pieces of heavy duty foil, long enough to fit all 3 racks, on top of each other. Shingle the ribs on the foil and tightly wrap making sure no air or liquid can escape.
Place the rib package on the unheated part of the grill (indirect heat) and grill, with the lid closed, for 1 hour flipping the package half way through.
Remove from the grill and take out of the foil. Oil the grates and place the ribs, meat side down, on the grill for 3-5 minutes until you see grill marks. Flip and cook bone side down.
Cover the meat side of the ribs with sauce at this point. After 3-5 minutes flip again and grill the sauced side down for 3-5 more minutes. Sauce the bone side now. Flip one last time to get the bone-side, now sauced, lightly charred.
Remove and let sit for about 5 minutes. Cut and serve with extra sauce.
