Combine in a bowl 1/4 cup brown sugar, 1 tbsp chili powder, 1 tsp garlic powder, 1/2 tsp cayenne pepper and 1/2 tsp salt. Mix together and rub on approx. 25 chicken wings. You can put these in a Ziploc bag and stick in your fridge for at least a couple of hours.
On your preheated medium high barbeque, grill your wings for about 40 minutes or until cooked thoroughly. While your wings are cooking you can prepare your hot sauce. In a bowl mix together 1/3 cup Franks Red Hot Sauce and 1/4 cup melted butter, 2 Tbsp brown sugar and 1/2 a fresh squeezed lime. When your wings are done toss them in your premade sauce and serve immediately. Don't forget the finger bowls.
