This swap takes an evening and is better than the early 930 stuff.

If you don't want to do this, you can significantly improve the early 930 brakes by:

1. Get some good quality pads (I like Pagid RS-29).
2. Replace your brake fluid with Brembo LCF-600.

You wont regret it.
unclebilly is correct as this is the set-up I did and have on my 73S..
I had my calipers machined and used spacers.. the rotors simply go on as normal. On the front, the calipers will bolt onto struts with 3.5" spacing.. you will need both the hub and the rotor.

Another alternative for early 930's would be the use of the Boxster caliper.
Its a helluva upgrade in stopping power, still a Porsche part, its Purdy, its light, and if you shop wisely it can be a lot more cost effective than the purchase of the 930 calipers, rotors, and required machining.

I am in the process of putting together a set of these for my cousins SC. Waiting to see what my machinist friend will charge for cutting the adapters so there may be extras available. Although they are currently available from several sources.. I just felt they were a little spendy.
