What is the difference between an unloaded, semi-loaded, and loaded caliper. I have been shopping online and this question came up. Does it matter what store I get calipers from? If it does, who should I order from. The car will mainly be a hot street car but will see a couple of trips to the SCCA track per year, but nothing too serious.
