Preheat a grill or the oven to 250 degrees F.
Pull membrane off of the back of the ribs. Sprinkle 1/4 cup of rub over each slab, front and back. Place ribs, meat side up, on the grill or in the oven for 2 hours. Remove and place each slab on a doubled aluminum foil square, meat side down. Combine the marinade ingredients. Pour 1 cup of marinade over each slab while wrapping tightly in foil. Cook for 1 more hour at 250 degrees F. Remove slabs from foil and sprinkle with remaining 1/4 cup of rub. Cook an additional 1 hour, uncovered, until ribs are tender.
Mix together the BBQ sauce and honey. Remove ribs from the oven and paint with finishing glaze, and cook for another 15 minutes. Cut and serve.
