So with plenty of cheap older 5 lug suspensions out there, and also Brad/Mueller's new hubs on the horizon, I am starting to wonder what brake upgrades are possible whilst retailing 3" caliper bolt spacing.
I have seen a few kits on the net that use a bolt-on adaptor and 944/964 calipers. Not sure which rotor they run.
Has anyone used a setup like this? Is it safe? Good? Happy? Cheap? Do I need a new M/C (they are 4 pot).
I have heard mention of 930 calipers too?
What are the options?

The radial mount adaptor doesn't look like rocket science.....
, make it for 3" boltspacing please

That looks like sufficient stopping power eh?
Mmmmm. Calipers.
Hmmm... I see what you mean. Not as simple as I originally thought.
What about BMW calipers?? Did they retain the same bolt spacing when they went to vented rotors?
Has anyone used Boxster brakes?
Haven't heard from Rich Johnson in a while, but I know he had a Boxster brake upgrade. He's one of the early guys on -6 upgrades.

I updated my front with parts from him before the boxster upgrade was available. He modified 911 struts to take the brembo 4-pot caliper from a 944T. Add carerra rotors and the little 914 stops nicely. Not leaving well enough alone, am going with carerra rear calipers too...
You can see the strut in the first picture of my old thread: http://www.914world.com/bbs2/index.php?act=ST&f=2&t=342.
Gotta go with 16" wheels or bigger with either conversion.

Instead of the Boxster calipers, you can use the 964 or 944turbo front calipers (which you can find used for around $200 / $250)
The bolt spacing is off by something like 2mm (for 3.5" struts) which is easily taken care of
Like the Boxster calipers, they work with the 24mm 3.2 Carrera rotors ('84 through '89)
cheers,
