If you want an upgraded pad Summit has a semi metallic Bendix and should meet your needs without all the swapping around. The rear organics should be fine, short of serious corner carving. Make sure all the spring hardware is in good shape, it's easy to change and not expensive. Check the backing plates for grooves where the shoes ride and the wheel cylinders for leaking. Check and replace the hoses and flush out the old brake fluid. Basic stuff that will make a big difference in brake performance. HTH, Steve
