Paul, Wilwood does make several disc kits for the Impala, although they are all vented rotor style . I put a set of their Dynalite Pro 11" brakes on a friends '67 Biscayne . .total bolt on .
The only down side for racing is the slightly heavier rotor which is .13/16" wide instead of 3/8" might be a good thing on a 3800 pound car having the vented rotors
