I wasn't addressing what the original poster had, merely what came on the 914-6es.

Mueller had all four corners on his car re-studded in the 5-bolt pattern. Kept the stock 914-4 brakes, but at least he had five-bolt wheels without those cheesy adaptors!

You'd have to do quite a bit to use stock 914-4 calipers on vented rotors. Not worth the hassle at all, IMHO. Just try to find the caliper half spacers--it's easier to just find a whole 911 front end...
