Just curious what everyone that converted to the C5 set up is using for calipers. I have been looking over craigslist, eBay, rockauto, summit....... you get the idea for a some calipers. Im thinking the best option is to buy some remanufactured units or new from summit. Should I stay away from those remanufactured pieces? Anyone have anything good or bad to say about their experiences with calipers?
