The Mintex AF brake lining is pretty close to factory equilivant. It is better, but not by a lot. You probably will not see much improvement.
You may go through brakes faster than I do, but I didn't need front brakes until 150,000 miles. I don't think I would bother to stock up for the future since you will probably be able to find a good buy closer to when you actually need them. Thats my $.02
