I saw a 6/99 Cycle World mag ad for Ferodo Superlite SuperHawk 320mm front disk kit, which bolts right on, and includes adapters to use the stock calipers, sold for $750.00. Ad further said they were castiron but within an ounce of stock, and the adapters were billet aluminum. Anyone done this or know more. The company hdqtrs is here in my town so I plan to get more info on my next days off later this week.... Also plan to ask if the Gixxer three piston calipers will work too....
