porsche 912 brake upgrade

Hi.
Can someone tell me where I can get the adapter block to convert my 912 brakes to the porsche boxster? Problem I'm having is my caliper is not a 3.5" spacing, is a 3" spacing.
thank you in advance.

Eric

I doubt that anyone makes a adapter block that can upgrade to Boxster brakes for a 912 or early 911. However, that being said, you could have some machine shop make you some adapters.

Most folks replaces the front suspension with a newer year to use newer brakes up to 1989. For a 912 they have gone to 911SC front suspension.

Brembo made an aluminum brake caliper with 3.0 spacing. They were used on Alpha Romeo's. This caliper also has larger pistons & brake pads. From time to time they show up here for sale. I can't find a photo of mine here is someone else's car

You must be making way more than 912 power or riding around with hippos in your back seat to need that kind of stopping power...

Historically the most common upgrade has been to put 911Sc struts and brakes up front and early 911 vented rears on them. Enough stopping power for even a 912 racecar.

That picture is the Brembo caliper on my car. It has a 3 inch bolt spacing and 48mm pistons like the aluminum early S caliper. All you need to do is get a short piece of ready made brake line. I got mine at Nampa, and from it. I use SC rotors. You can also take the spacer out an run solid rotors if you want to keep the weight off.
The caliper was a option on the mid 80's Alfa GTV-6 and Malino.
The fancy pad retaining pins are Porsche 908 repops sold by PMB in Utah. I was the first to put these on this caliper. When Pete Stout saw them when he was editing the article on my car for Excellence Magazine at the time he had Eric at PMB make him the second pair for his 914 converted to a 914-6. They are overkill but kinda cool looking.
Sometimes Centric lists rebuilt ones on ebay.

They are Brembo calipers on a Porsche. Aluminum with a 48mm pistons like the early 911S but with a 3 inch bolt pattern. That allows me to keep my original Koni struts. The calipers where originally put on a Alfa but a Brembo nun the less. Last I checked Porsche has used Italian made Brembo's for a while.
I'm not an elitist, if it's a good Brembo caliper and fits my car and works, I'm all over it.

Nice! I'm about to repaint my Koni struts. They look a little road worn.

Myself, I went for the 3" spacing ATE calipers used by BMW to go vented instead of going the SC route.

What BMW has those calipers? 320i?

If you seriously think you need a front brake upgrade then why not just use the stock wide M calipers for vented rotors? Cores are cheep, rebuild kits are readily available and they are Porsche.

3" mounts
48mm pistons
282.5x20 vented rotors

That rotor size was used all the way up into the SC model. Most likely enough brake for a 912 canyon carver.

Yes, '77, but read up on it (solid disc Porsche folks have been doing this swap for years) if you are considering this route. They used 3 different calipers and the Girling and non vented were the ones to avoid so verify before ordering as they go by a production date cutoff. There are some minor modifications that need to be made, though nothing that requires real machining or cost, and work great with the Porsche vented discs.

"why not just use the stock wide M calipers for vented rotors? Cores are cheep, rebuild kits are readily available and they are Porsche."

Out of curiosity what does a warrantied rebuilt pair of "stock wide 3" mount M calipers" cost now days without cores to trade in?

Nope!

Those are for narrow (solid) discs.

I answered that question on my last post:

"Yes, '77, but read up on it (solid disc Porsche folks have been doing this swap for years) if you are considering this route. They used 3 different calipers and the Girling and non vented were the ones to avoid so verify before ordering as they go by a production date cutoff."

Not trying to be vague or mean, but you have to be diligent when it comes to things like this as brakes are an important thing.
I don't want anyone to go into this type of swap without looking up a forum thread that already tacked all the questions and issues and come back and say I told them wrong

There are too many flakes on the internet giving bad advice.

If you just want a drop and go solution do as was suggested and get stock Porsche parts.

I did this swap 3 years ago and found most of the info in existing threads.

My reply in this thread was to mention this as a possible swap for 912/3" but as I mention am hesitant to give procedure advice here for reasons mentioned.
