This is a pair of used Wilwood 4 piston calipers with brackets and lines. These came to me along with a number of parts out of an estate. The owner was building a 1972 nova and I think that is what he collected these for. The brackets are part number 250-8917 as shown. They show as being applicable for C6 Corvette but many of these Wilwood parts were also used in their kits and on custom applications. I don't see any part numbers on the calipers. They are polished and have some light scuffs and scratches from storage as shown. The lines have Wilwood printed on them as shown. The brackets themselves sell for over $200 each through Wilwood. These are a great start to a Wilwood disc brake setup.
