Every single Summit brand item I have purchased has never failed me in quality or workmanship. Never bought any of their rotors, though if I had the need I wouldn't hesitate to purchase a set.
they worked out great, i like them alot. they make a cool sort of whirring sound when i hit the brakes.
i did not upgrade the calipers, but i did paint them. i'd have some pics of them. but i lost my camera and i don't have any money right now to buy another one.
