Do you think these will stop a 3.6 conversion ok???

Gen-U-ine Porsche 930 Calipers, new in the box!

Stock 914 front calipers seem.....well...um.....a little small?

OMG... I just had a small heart attack.

You could sell them and buy a 914... -6

Let's just say they were a few hundred less than I paid for my first 914 (in '78)!!

There has to be a story attached... SPILL IT! LOL

I'd love to have more detailed photos. Black anodized. Nice. I think I can source all of that refinishing stuff, I always wondered what they looked like new.

Thanks for posting

(can I come by and touch your... calipers?)

Sorry Eric, they were out the door the next day. I just got to touch them and take pics. This was all I got. I do have some higher res versions if you want.

Those monster fronts (two on the left) were just .95 lb more than the stock front 914-4 caliper.

These are for a customer doing a very nice 3.6 conversion car, out east. The desire is to build a most awesome 6 conversion with as many NEW factory parts as possible. Making it as close to a new 914-6 as they can.

The customer has a 930, and wanted to put the same brakes on the conversion car.

Both front and rear are four pieces. The two center sections, and then the inner and outer finned sections with the pistons are bolted to the upper and lower centers.

That's the beauty of those later calipers. I often marveled, over the years, how they got better at economies of scale. Every part in there can be turned around and used left or right.

Seems no matter what you got, there's something better out there to lust after.

Jon, I'm guessing you have something else to add to next years letter to Santa

They will work, but you won't like them ... BTDT ...

Go with Boxster Calipers front/rear instead. They need adapters to work, but they're much better than the 930s ...

Those would just be so right on an IMSA 914...

John

Oh no... I am happy with what I have

I was planning to go with 356 drum brakes...they are aluminum.

Except, i was serious.


He's going to mount the 930s and he's going to hate them. Mark my words, you heard it here first.

Like i said, BTDT ( <- stands for "Been There, Done That"), the 930s suck.
You'll never be able to get them "feel" right.
Andy

I have some standard 3.5" calipers now....They will lock em up no sweat! Why would you need more?

Those puppies represent a couple sets of new tires which I need more.....and so does Andy.

Wow, those are pure sex. Not that I need them or could afford them but my god they look soooo gooood.

Those are sweet!

Why?
Are they to much? He is upgrading the motor so he may be going a bit faster...

Seriously...what is the issue?

Rich

I have them on my 911 and really like them a lot. You do need to run a much bigger master cyl ... 23 mm ... Mine did not look that nice though ...

Yes. I know.

I wasn't referring to a technical problem. I know how to mount them. I know what MC to run. I know all the technical aspects to make them work.
BTDT.

Then, you run them hard and you realize that in a 914, which is significantly lighter than a 930, you can't modulate them the way you want to. They don't grip well with little pressure, then they grip too hard. Tried different pads and compounds. Some made it better some made it worse.
Never got to the point where they felt comfortable.

Finally switched to boxster calipers front and rear and had instant success with grip, feel and modulatingability (i'm making up words here )

All this on a 914/6 car set up for club racing with a warmed over 300+ HP 3.0L motor ...
Andy

Here's what I plan on using on my 3.0 conversion. The slotted Carrera rotors were sent to Diversified Cyrogenics and were "frozen". The fronts are C2 fronts and the rears are C2 Turbo rears. Plan on using Hawk street compound on the street and a racing compound on the track. (not autocross) Also have a Tilton brake adjustable valve mounted between the seats for rear adjustment......

While beautiful, they are huge for the small pad area. I understand wanting to build with as many new Porsche parts as possible. It should be a nice car.

But those calipers look like a bad example of over complicated engineering. Four pieces bolted together, just scream movement and flex. I imagine you will get a better feel from late Model Brembos, since they have benefited from more modern materials and designs. Plus they would be even lighter, have staggered pistons, be more compact, and just look more elegant.

Since he is using them under Fuchs alloys, probably, I guess it won't matter.

That makes sense...so the larger setup was in fact to large.
To binary no matter what you did.
The boxster brakes are just right...or at least not as on/off and the 930 setup...

BTW, can you write this in German "modulatingability"
Those were the words that pissed me off trying to read the morning paper over there...all the newspaper writers thought up new words every day....threw me completely off trying to figure out what the hell they meant.

Rich

Odd... same pad (345 block) and piston sizes (I believe) as the Boxsters.
