You might look at replacing the stock
2 door calipers with 4 door calipers, I
took a set off of a 4 door in the wrecking
yard, I grabbed the whole assembly that
bolts to the knuckle, I think you need the
mount to retro the biger calipers, but with
bigger tires, the 4 door calipers make a
big improvment in stopping power
