I didn't know there was such a kit. I'm planning to put Billet Dynalites with 12" rotors (fronts) into Trigo wheels on SN95 spindles. I've carefully measured to see if the setup will work, using my rotors (turned-down Corvette fronts) and calipers inside an actual Trigo S/C. It looks as if it will work, but I need to save every 1/16" I can so there's room for some wheel weights also. In order to save space, I'm (1) narrowing the calipers' aluminum body spacers to reduce the width of the calipers and (2) making up a set of custom adapter plates that allow the calipers to really hug the perimeter of the rotors. The adapter plates can't just bolt onto the SN95s. I'm going to have to weld on some little pedestals, then bolt the plates through onto the spindles. We're in the process of doing the machining now, then I'll have to make up the plates, so it'll be a number of weeks before I can see if everything really fits. I'll try to post photos when they're finished.
