Wayne,
the ultralite set up has vented rotors. the p/n for the whole kit is 140-2129-B. This is the kit the Weavers install on the Unique cars. Go to their website for some pictures of them. I am currently involved in the installation of this setup. Wilwood calls out for a master cyl bore diam of 1 1/8". We Plan on using a Corvette master cyl, which has this diam.
