On my current conversion that has 5 lug hubs and 914-4 rear calipers, I used 911 solid rotors and had my local repair shop take 2 mm off the radius. It fit perfectly and you can get 911 rotors at flaps for $50-60 each. I use 912 M calipers on the front with solid rotors but most people would use 911 M calipers on the front with vented rotors.
I used stock 911 rotors because you can get them turned anywhere. To turn a 4 lug rotor into a 5 lug, it needs to be set up on a mill.
Thanks for the tip Mark. This is what I'll do. Now that I know this, I'll just do it myself.
