Kirkhams use ( rather the older ones did. Not sure what they use now) Wilwood 4 piston calipers. I know the rears were Dynalite calipers but I'm not sure what the fronts were. However, my point is that the Kirkham I drove had excellent brakes and very balanced under hard braking. You could contact David Kirkham on this site and talk to him about switching your brakes to his set up. They may bolt on but he would know.
